Mamiya lenses on a 645N

I have some Mamiya 645 lenses I would like to put on my Pentax 645N. I wonder if it might be possible to change the mount somehow. I'm not worried about stop-down metering but the 145SF, 55shift, 500/5.6 might be interesting.

I don´t think that Mamiya 645 lenses on a P645 body are possible.
The flange distance of the Mamiya (63.30mm) is smaller than P645 (70.87mm) so a Mamiya lens would´nt focus to infinity
Auflagemaß ? Wikipedia
Sorry for the response

(The other way (P645 lenses on a Mamiya 645 body is possible)
