New projector build - how much space for this setup? need to make most of area

[rich0550]

I am thinking maximum are for screen would be

93" high, 164" long, 67" deep...

What is the most I could make out of this area? Right now I have a single DA-Lite 116" long wall high. I know this is a tight space for a curved screen of this size. What can I get away with in terms of curvature? How close can I get the projectors? I cant back project. Would need to throw almost from 6' away? Trying to keep that nice immersive wall size type of screen. Is this possible? Super expensive?
