I want this to take place in the RPM universe, as a sequel season.
The powers from Go-Busters are retained along with the "you got powers from the accident" comcept, and it works because the Rangers are three teens from that school Ziggy and K started. The teens were mischievous and got ahold of Scott's "Cursed Morpher" and released Venjix again.
However, since RPM, the world has rebuilt to prevent Venjix or something similar from ever happening again. Venjix cannot destroy the world again.
But now he doesn't want to. The Morphing Grid, while impossible for him to corrupt because it's too "Absolute Good," did show him King Mondo and his rise to power. This causes Venjix to want to escape to the main dimension and join the Machine Empire.

The rest of the season is him trying to escape and eventually succeeding, because the Machine Empire will be continually hinted at along with the fact RPM-World knows about the history of the Main-World's Rangers. And while the finale destroys Venjix again, he pulls the same thing he did last time he was "destroyed."

Guess what this would all explain...
