So I posted this in another thread when someone mentioned tearing down the strip mall on 7th and University.
It's not exactly the best or most accurate design, but I think we could still have a roundabout on that intersection if we stretched it like a football and altered the roads entering in. I still feel there's some room left to make it happen.
The red, obviously, is the actual roundabout. The blue are the other roads (with the existing Camp Bowie east to south on University exit staying intact. The green is the space between, of course, and I didn't add it in to the West 7th side between the strip mall and new Chu Eyeworks, but you get the idea.
As for the yellow and orange, it's what I would think would be a hotel or residential building. Yellow being the building and orange being a 3 level garage.
It would take time, major planing, and some headaches to build it, but I think it could benefit the area by easing time waiting in traffic. There could also be an opportunity for a monument or fountain in the middle and unique signage like what you see in Houston's Galleria Area, only it would point to the direction of each road.
