I am not interested in more bodies that are not Pentax. I have 5 Pentax DSLR bodies, along with a Pentax ESII, a Fujica and a Minolta (SLR) bodies. I ran across a Nikon 500mm f4 F mount manual focus lens in nice shape for less than the Pentax 500mm f4.5 SMC K mount manuals offered around the internet. I was just wondering if I could mate it up with an adaptor. It is supposed to be a fine lens for its day. I found some Sigma 500mm APO lenses also. Just trying to not pay what Pentax A* 300mm f2.8 and Pentax teleconverters in real good shape are going for these days.
Thanks for all your input. Thats what I like about this forum, you can get great input without being clobbered in the process.

With that as the context, I'd say you have some choices.
1) mount the camera to the large telephoto using the "twist and pray" method. This only works with non-ai lenses, unless you modify the Nikon. The lens can be shimmed if you want to try to get focus distances to match up.
2) if you can find one, the Adaptist mm+ mount replacement is a good option.
Pentax K+ Multi Mount - Adaptist. (note: the mount is specific to weather resistant and non resistant and except for the k-500 which uses the wr type. Also using these mounts doesn't preserve wr.
3) leitax convert the Nikon mount.

Assuming the lens has a tripod ring and is used from a trpoI think method one or two could be reasonable a try. Option 3 is an excellent choice when only a couple of lenses need this.
