I could see a use for Army fixed wing ground attack aircraft used to support SOF elements that is controlled by USSOCOM.
Budget wise I have no idea if it's feasible and I have no doubt that good idea fairies would jump all over it and drive the price through the roof even if they went ahead with it. I know they wouldn't be useful for big war, but SOF does a lot of stuff where there isn't really a need for an aircraft carrier to stay off shore waiting for them to call for help, but it's stil fairly dangerous. Case in point is that SF team that got hit in Nigeria a while back.
Having a couple of cheap rugged ground attack planes that could deploy in country to support them seems like a reasonable idea to me.
I think Army fixed wing SOF elements would face the same logistical problems today as the A-10 when it became operational that's why IMO rotary wing is the right call..
