Wow! That would require a VERY short focus and very large lens. If they exist at all, they will have quite some distortion. And/or be VERY expensive. I don't think it is doable, unless you have unlimited (military) funds.

The distance of 60 cm is optional - this was an ideal way.
The main goal is to make the projection system that will fit in box sized 1200x900x800 mm, with the screen size 1200x900 mm
