Mounting Mamiya 28mm f4.5 Aspherical AF D lens on Mamiya 645 film mount

I’m looking at mounting a Mamiya 28mm f4.5 Aspherical AF D lens onto a Mamiya 645 film mount, specifically for video use on a Kipon focal reducer adapted to L mount/ E mount cameras. The reason for this is to find a wider rectilinear 645 lens than 35mm. The 28mm should cover this size.

I believe some manual 645 lenses are compatible with the digital 645 mount but i’m not sure if it’s possible vice versa.

I understand it won’t be possible to adjust the aperture of the 28mm when adapted, but I’m wondering if it’s possible to keep the aperture on 4.5 and use ND for exposure control.

Thanks in advance.

Robbie
