Adapter to use 645 lenses on 67 camera

Having just purchased a 645N camera I have bought an adapter so I can use my 105, 135 and 200 mm 67 lenses on it. I was just wondering if I could use the 645 lenses on the 67. I only ask as my 645 lenses are zoom so it would be nice to experiment with them on the 67. However, having searched the universe and beyond, it appears that there is no such adapter. My question is why? Is it not possible to use them this way or just that no one wants to put 645 lenses on the 67?
It's just that I have got it in my head that there must be something technical I am missing as to why I can find no adapter. Any ideas?

The 645 format is smaller than the 67 format, so 645 lenses will not cover the area of the 67 frame. In just the same way, a crop sensor (APS-C) lens won't cover the area needed for a full frame model such as the K-1.

Hope that helps!
Best regards, John
