We have an old (rear) projection TV you can have. 72" 1080p, IIRC. But you'd have to come get it.
However, I don't think that would be a step up these days.
As far a projecting onto a wall in a room with plenty of daylight, that would not be recommended.
Good high-resolution bright projectors could cost you more than a good big-screen TV. You say you have room for 100" diagonal easy. Is 96" the biggest flat screen so far or do they make bigger ones nowadays?
IMHO, you'd get a much better picture out of a flat screen TV than a projector image on the wall. Plus you wouldn't have to worry about bulbs burning out frequently, people walking through the beam, watching dust swirl etc.
