I don't think it'll really work anymore.
Regardless of how often Linkara tries to point it out, the series aren't considering themselves in continuity with each other anymore, and beyond token lines in the crossovers, they are, for all intents and purposes, completely separate universes.

Trying to implement this story now will probably lead to more plot holes and continuity gaffs just to have guest appearances and etc.
