Changing health/defense when getting in/out of a mech

Recently I've been trying to formulate the various battle systems for the game I'm trying to make, however I've run into an issue.

The way I want my game to be set up, I want it to be where the player character can walk around on the map and engage in side-view battles. However, the player also has the opportunity to get into a mech, and those battles are front-view. I already have access to a script that would allow switching between the two battle systems. However, is it possible to make it where when the player gets into a mech, their health/defense/attack power changes, and when they get out of it they go back to normal? This also kind of relates to whether it'd be possible to make it to where the player's mech would have an equip screen of sorts.

You would just need to change the player's class to the mech class and vice/versa. That would handle all the stat and skill changes easily.

Ahhh thank you so much!
