If you want, I still have a filter wheel from my DCB II Live leaf in my cellar, waiting for such a project......
Will probably need some work to get the electronics done to advance the motor stepped right, but not a real big deal.
I think that can be done with a days work or faster.
Does anyone remember the Kodak DCS 420 ? there was exactly such a setup, so this is not the first one.
About the expected image quality I´d say comparable to a 30 Mpix back probably. Maybe with a bit cleaner color.
