Oh, the corrupting power of found money! Sorry, found shutter.

Play is good, so is keeping busy, but enlarging lenses typically cover around 50 degrees and are of normal construction. When a lens of normal construction is focused to infinity, its rear node will be one focal length from the film plane. A 50 mm enlarging lens will cover 24x36 at infinity with a slight margin for movements.
If you want to use w/a lenses on a box with P67 register, you're pretty well limited to lenses for the P67 and for 6x7 cameras with longer registers.
Good luck, keep on scheming and plotting,
