Leica M mount to others

[PetPhoto]

I have to ask, I have other cameras and mounts my range finder fun is comprised of a new to me leica m3 "budha ear" mdoel and a voightlander vitomatic II

I have other cameras of FD and M42 and K mount, I have 1 m mount lens at the time. The other mounts really dont have options for lenses anymore, not able to use auto focus crap ya know.. Anyway, there are some good lenses for digital M bodies that wont work on my m3, but are affordable enough to make me wonder if i can get them working on an FD or K mount or M42 mount.

One i think most interesting

but with the mount adapters, can i get full function on an FD or k or m42 camera

Any SLR body is thicker than a Leica or other RF body to allow for the mirror that relays the image to the ground glass for focusing and viewing. While you may find an adapter that allows you to physically attach this lens to an SLR body, it won't focus to infinity or anything farther than a foot or two from the camera. Since a lens like this doesn't have an auto diaphragm then auto stop down can't work and f/5.6 won't make for a very bright ground glass either.
