Go on Nittany...
...you were about to predict the future.
Hearing Osprey pilots cream their pants at the opportunity to mount weapons on their aircraft makes me scream on the inside and die a little bit as an attack guy. You can make a fighter an attack aircraft, or vice versa but an assault helicopter will make shitty attack helicopter for various reasons. I think the Russians have proven that self escorting assault support aircraft are not a good idea (Mi-24). Reinventing the wheel.
This is more of a Harvest Hawk or AC-130 analog than an escort platform, but...
But when Harriers can't provide TOS and UH/AH can't reach, you do what you have to do.
I would hope that the CAS/escort role is broken off into its own sub-community of sort, much like the AFSOC C-130s are, especially the AC-130s. Providing close fires is specialized enough that there just aren't enough training hours to have pilots who are good at assault support and CAS.
All that said, the earlier comment about investing more in aircraft readiness holds true. If a 12-AC squadron becomes, say 8 assaults and 4 strikes, having 25% or more downed aircraft severely limits the MAGTF's lift capacity
