I think one camera for 120 film 6x9 and 6x12 with a couple of red frame number windows would be fine.

For 5x4 then just a simple box with a film holder on one side and a lens mount on the other. A bit like some of the 5x4 pinhole designs I have seen.

I think a single camera for all three formats would be a bit more complex than two separate cameras.
