Here's an idea for this that might be kinda cool, though I'm sure it would only work on Samus and Zero Suit Samus: Import a lower evolution pokemon onto Samus and import its higher evolution onto Zero Suit. Let's say, for example, put Ponyta on Samus and Rapidash on ZZS. When transforming it could give a kinda cool illusion Ponyta is evolving mid-battle. If there were a psa made I could see someone setting it up so Ponyta would "evolve" after dealing a set amount of damage and wouldn't be able to change back for the rest of the battle.
