Just to be certain I understand, you want 2 carriers in each convoy? Your reasoning being that the strat guys will have to sink 2 of them, giving you a few more minutes of furballing?
Not that I necessarily support the strat guys or furballers, but I don't think that's a very good solution. It's kind of a band-aid, because now they'll just send 2 guys over to knock out the fleet.
I think the real problem is the carriers are just a little too fragile. Every time I've gone after a carrier, either someone else has put 3000 lbs of ordnance on it already, or they're made out of tissue paper, because I can dive bomb one and with a single 1000 lb bomb and knock it out.
As a strat guy, I would want the carriers to be a bit tougher, because as far as I know, a single p-38 wasn't able to sink a ship with one pass. As a furballer, I would want the carriers to be a bit tougher for obvious reasons.
