I haven't read through everything yet but have you looked into Dean college in Franklin, MA?
I don't have one attending there yet but I think it is a perfect college for these type of students at least from what I can tell.
We are still crossing our fingers that my DD will graduate and she was accepted there. It wasn't her first choice but she didn't get in her first choice due to academics (I knew she wouldn't) but when we went to visit, I loved it.
I really think she is going to find her niche here, it isn't a school most people hear of (you should see the

looks we get when we tell them she is going to Dean college in MA).
I found it via a search because I was looking for something simlar although my DD is a performer, she also does tech and when we went to visit, we had an unexpected tour of the light booth and her and one of the advisors was talking tech stuff while my sister & I were over there going "have no clue what the jargon is but they are enjoying it"...I know they have a tech side and they also have a Theatre Management program which I don't think many schools have.
I wanted something that focused more on theatre than schooling per se because yes, my DD goes to school so she can perform & unfortunately the town we are in is very little emphasis on the arts in school.
You know the school is more arts than anything when asked on the tour (it was a dance major taking us through) about sports and the answer was "our golf team is pretty good"....

They do have a football team but apparently it is more for the dancers to perform than the football players is the impression I got.
