What other Sparking Episodes would you want to occur if a sequel were announced?

I want to know what other scenarios you think they could do for a Sparking Zero 2. Cause I feel like they ran themselves into a ditch here; what other ways can you make a what-if Raditz interesting? And while there were a few ideas that could've gone somewhere stuff like "What-if Piccolo" just rerailed themselves back into the main plot. "What-if Goku killed Freeza" ended right before it could've been interesting.

I don't know, maybe I'm wrong. What do you think?
