I was wondering: if you had the foam on mobile panels that were a few inches from the wall, would that still work? I was thinking of using room dividers and putting foam on them:

It seems like you would also get some non-scientific diffusion, because the panels from the room dividers would reflect the non-absorbed sound at angles rather than directly back. Maybe perhaps, they also could serve as a bit of a bass trap by trapping the bass in the airspace between the room dividers and the wall.

But I don't know if you lose a lot of absorbtion efficiency if they are "floating" away from the wall like this. And studio acoustics is a complex topic in general. So I'm wondering what the general concerns might be for this wacky idea.

Thanks!
You have so many misconceptions. Read the chapter Absorption in MHoA.
