I think anyone can use the shape-change item but --- I never thought to see if the specific talents worked. Something to try! Of course you would need "pet pal" and some dialogues are opened only by specific characters. If you have Sir Lora (or whatever the dead cat-riding squirrel's name is), the main character has to have pet pal to unlock those dialogues. Some dialogues are only for main characters. I'm with Stabby - I doubt it's feasible.
