It seems to me, when AH revamped leaving out the Early War, Mid War and Dueling Arenas, the drop off of attendance
began... I may be wrong but that is my thought...
Bunch of stuff changed at once around then iirc. Those arenas (DA barely excepted) weren't providing any benefit I could see, at best all I ever saw in them was a couple people farming perks.
As to the OP, I'd be all for it if it were just a matter of waving a wand. I've very often wished to be able to fly a Bearcat in here. What I've also always wanted was the truly bizarre experimental stuff like the Do-335. Bring on the weird and wonderful freak fliers.
But y'know, like you said feasibility of stuff getting done... *glances over at the Tempest model*
