I was watching Dean's G15 on a perferated Grayhawk (with ISCO lens)
on a larger screen than you are thinking of. I've a G1000 and I'm
currently thinking of a Luxus Model A Electriscreen 96"x54" screen.
It's tab tensioned and motorized. I've an open beam ceiling and I'm
trying to figure out how to mount the thing and get power to it. I'll
be getting a Panamorph (I hope) someday in the near future and I figure
it will be bright enough. You should have no problem with a G15.
Give Stewart a call at (800) 762-4999 or (310) 784-5300 and they
can fax you more exact measurements of the enclosure(s). Very friendly
Good luck on your choices.
