This works fine with either Paterson or the Samigon/AP/Arista Premium reels and Kodak 120 films (I do it with Plus-X and TMax 400).

There is at least a bit of space between the end of the first roll and the beginning of the next.

I wouldn't suggest doing it with rotary processing - in my experience films are more likely to wander with rotary, and may end up overlapping.
