Subject: Nikon to Leica Screw Adapter?

How about an adapter that will couple a Nikon AIS bayonet
lens on a Leica screw body? The Nikon lens needs to be 18mm from the flange
on the screw body to the lens mount. I arrived at this by measuring the
distances between the film plane and the (front of the) lens mount on the
body of the leica screw and Nikon (FM2) cameras. It could easily be done
with a screw extension tube epoxyed to a modified Nikon back cap. The
hard part is making it couple properly for non-wideangles with limited
hyper-focal setting is harder. 

I got the idea from a friend who made a "sheimfluge" adapter to get more
DOF on a Pentax 6x7 lens at close range by modifying a body and back cap to
make an adapter thats tilt the lens. Of course that was for an SLR.

Any insights, or life-threatening comments on this?

Thanks,
