You're talking about a generic COW driver. That would be a good idea.

Not hard. It would involve splitting the COW stuff out from the ubd
driver and specifying the device that it's to be layered out somehow when
Splitting that stuff out would be good from a structural point of view
anyway, plus it would make it usable on native kernels.

Yep -- that would be it... Personally, I'm no kernel hacker (and no
filesystem guru), so while I'd be keen to use such a driver, I see
myself as entirely unable to make it happen. I could do some testing
once it's nearly ready though...
How hard would it be to adapt the COW driver to be generic?
