1. Yes, that's completely do-able! Characters are allowed to regain canon powers and kaisou-original elemental powers side-by-side! It's mostly a matter of how you want to spend your regain points each month. How much the character ICly struggles with balancing both is completely up to you! He won't have to give up his fire power for his geo vision at any point.
2. It is 100% possible and in fact has happened plenty of times B) Tell "your friend" to go wild.
