I like your idea better, that would be a darkly humorous twist and give a chance for Zeno to show off his power.I think a far more realistic version of the outcome of this arc in terms of consequences is Goku calls OmniKing/OmniKing finds out about this somehow and at the end destroys all the time rings - wiping away all timelines except for the timeline we know.
No matter what happens, there has to be some kind of consequence to all this. This arc has made the concept of timelines in DBZ so convoluted that it's almost not even worth attempting to think about it.
