This has been what we have been doing more or less, though i think the concept as a whole is pretty much outdated.
First off; dictors and ceptors are obsolete, there is no reason to have them in gang any more, apart from maybe one ceptor, that knows what hes doing. Normally we use covops for warpins, and tackle is easily accomplished by the hictors and proteus in gang. Assault frigs are not as good as legions for popping bombers (we use 2 RSB's and the scan res sub which gives them 3000 scan res, meaning any bomber who lingers for over a second dies)
Thats pretty much the first part of your list of ships. Aside from carriers, which wont work any more, and can be augmented by guardians, and of course our huge blob of motherships, running the same role on the armor hacs. Well i say they wont work, personally the only role i see carriers needing to play in any substancial role is when we are in a dicey situation with our motherships.
As for arty abaddons, tbh i have never liked them. They dont really track enough to fill the role that you want them to, and if you substitute the roles of the other tacklers/support for armor hacs, which, surprisingly, have turned out to be incredibly adequate sniper BS killers, although they do stick on LRH's, then i think personally the role that you wanted them to fill is much easier to deal with using an armor damnation with probes.
You MIGHT be able to persuade me that using some armor tanking machs in the same role would work, however i see a few problems with this
Оnе is that they will ALWAYS be primary‚ and lacking the sig tanking bonuses of the smaller zealots, we may have trouble keeping them alive. Think rather of them not taking twice the damage of a zealot, but probably 10x more, as everything will hit them much harder, and i wouldnt be confident that any battleship could survive the things that we take the HACS into. After flying guardians pretty much exclusively for 2 months i think i have a much better knowledge of most of how these ships tank, and tbh, i dont think the engines could take it captain.
Bombs will rape them.
Also, there has never been a time, at least when i have been in a fleet, where killing someone 100km away would really have helped that much. Оf coursе‚ killing falcons and scorpions would have helped in some fights, but i dont think it is a justifiable role to fill when we could have those people in zealots. Most of our guys fit remote eccm on, and we use caldari and amarr jammers, and unless jammed by a pos, i have never been jammed in my guardian. Most of our decent FC's now have a prbing damnation in gang, and with 20 seconds of something coming on grid, can havet he entire fleet right on top of it.
Perhaps the role would be better filled by using sniping legions instead? Without looking up what fitting could be used, I dont see any reason why we could not have all the legions in gang fit beams.
I guess what im trying to say is 10k alpha, while useful is not really needed in armor hac gangs, where nine times out of ten, we have enough zealots on top of a target to finish the job.
Personally I see eve 0.0 combat as 4 definable categories at the moment;
1)Supers, with AHAC support; for most situations where we are comfortable, this will more or less counter everything. The only thing this has trouble with is highly mobile gangs like LRH's, but these dont pose any threat to a well organized gang.
2) armor hacs, exclusively. If you have more than 50 people in gang, you dont really need anything else. They can pretty much take on any other type of fleet, bar long range hacs, but long range hacs cant do anything to them really, not unless there is 50-60 munnins or something.
We were discussing on teamspeak earlier that in fleets over 80, we could probably change over to beams for the zealots. Though i dont really favour the idea, i think it deserves to be discussed.
3) long range hacs. LRH's are still very viable in my opinion, though it really needs to be discussed again what type of ships we want in these gangs. Normally we use these if our gang strength is under 30, or we know that our opponents will be in armor hacs. We use them against armor hacs so effectively because most people still havent worked out how to use armor hacs yet, I can say with reasonable confidence that if faced with an armor hac gang we would only lose retards. However, i think if refined we could start using LRH's again as a very effective counter to armor hacs on a larger scale as the kill to loss ratio will always be pretty good (K

hurr)
4) close range BS. Personally i think they have a limited value, though can stil lcome in handy on capital ganks where a cyno jammer is online, and for a hard target kill like a cyno jammer
There is a fifth, but personally i dont really rate sniper battleships as having any useful role at the moment. Possibly pulse apocs, or arty machs (althouth really i put arty machs in with LRH's), but standard sniper battleships dont really have a percievable role in PL's fleet 'doctrine' right now.
Ive probably missed some shit out so feel fre to call me out on it, I was just trying to clear some things up, you probably already know most of it.
Re-reading through all those

im not sure i really answered any sort of question, but what im trying to say is the general idea is there in the ОP, it has just bеen refined for practicality over the time between now and then.
