Good idea, but even with my puny scripting knowlege I know that when combining scripts you must consider "script compatibility".
Also the mystery dungeon battle scenes aren't exactly the same at all. Most of the battles in PMD happen in maps without transitions.

Explorers of the Sky.
I'd also hope that this kit has some sort of dual screen in order to add more functionality to it (Like in Time/Darkness/Sky).
