I think, no system can use 2 disk which have the same UUID at the same time (besides maybe one of the Windows BIOS fake controller). Duplicate UUID is a contradictio in adiecto and should be fixed.
Just a guess, but it probably could, if you didn't use the UUIDs to mount the drives by. Such as you mounted them by device names, or volume names. Though, I think it'd be best not to have cloned IDs.
Briefly looking at RAID information, there are things that should be unique, and there are some things that can be duplicated (not so sure that they should be, though). Drive IDs would need to be unique for anything that uses IDs to differentiate one drive from other. There's partition and volume IDs that are used for different purposes.
