Figure Player type change

Hello all, my friends and I are doing an amiibo tournament. I am using a Bowser which I have used Absolute Safety Capsule on to max its defense, and it has ended up as a Shield type. I noticed that he's very good against enemy Shield, Attack, and Neutral types but loses to almost all enemy Grab types. I want him to be more consistent against all types, so is there any way to change him to Neutral type? Thanks!
