I'm not entirely sure this idea will work. As always I HOPE it does. But switching between decks to whichever is more advantageous seems like that alone will make it too powerful. If you really want to do this, and it doesn't work the way it is, you could change one of Pit's talent cards to allow you to switch between ranged and melee with purple and red decks. Similar to how my Bastila deck does with Jedi Knight and Sith Apprentice.

The normal 5 talents look fine.

His Final Smash could be cool. I've thought about doing some sort of "summon" card like this but never actually tested the idea. I hope it works. My only worry is that the Centurion's attacks are all 3. This means opponents know exactly how to defend. I would recommend allowing the Centurions to use Pit's basic cards to attack.

That's it for this deck I think. I would recommend looking back at some of your original decks and comparing them to the newer ones. Do they look balanced compared to each other? I haven't checked, personally, but it's just a good idea on these large projects to make sure nothing changes while you're working on it.
