I need a solution for vertical image drop for a living room projector in this configuration:

- projector mounted in lift concealed in 12' ceilings
- 106' diagonal screen with a desired drop of approx 60"
- approx 12' from projector to screen

I see three opportunities to shift the image to match the 60" drop:
a. Drop the projector on a scissor lift
b. Find a projector with 100%+ vertical lens shift
c. Angle the projector and use LOTS of keystone correction

Is it realistic/wise to solve this with only b. and c.? In other words, should I try to solve this without a scissor lift, or is a scissor lift a must? Thanks.
