The lenses are also angled so that they converge on a 65" screen. When you go to a 92" screen and the associated longer throw distance the lenses won't be all aimed at the screen. Front Projectors allow the angle of the red and blue guns to be adjusted for the screen size, RPTVs don't.
You would also have to redo geometry and convergence from scratch, not to mention mechanical focus and Scheimpflug (another tricky thing since it's not generally adjustable on RPTVs). The lenses may not focus onto a 92" screen.
You're probably better off getting a projector.
