Is it possible to edit CSPs and SSPs for Giga & Co. and Stage Roster Expansion?

[(specter)]

I want to make the Alloys, Giga Bowser and Warioman have their own CSPs without having to share the same one of the character they're based off of (i.e. Red Alloy and Captain Falcon have their own CSPs). I also want to know if I can edit the stage pictures and whatnot of the Stage Roster Expansion stages. Is any of this possible?
