Shift lenses

I finally hung from my ceiling the six-foot silver lenticular 
screen from Dalite (sp?) I got a while back on recommendation 
of folks on this list.  Wow!  The thing is bright and sharp!  
I can fill it with a 7-perf from 20 feet using 4" lenses.

My ceiling isn't all that high.  I've located the projector at 
an elevation half way up the screen.  Now there's no place to 
sit at which you don't block the beam from the projector.  So
now what?  Obviously I need shift lenses so I can position the 
projector up high above the audience.  That's what my brother-
in-law has on all his projectors and they work great.  

Anyone here done this with a 3D projector?  Recommendations?  
I don't think it would be too hard to raise the condensers a 
little and the lamps a lot and tilt the spherical reflectors 
but I'm not too sure about finding projection lenses with 
enough coverage.

Thoughts?

Thanks,
John B
