Can you change accounts?

Hello there, I have a dumb question.

I have a PS5 Overwatch account I still play on that’s been active since 2017.

I made an alt account a long time ago that I never really used but I liked it onto my Nintendo switch 2.

(Originally a PS5 OW Alt Account)

Is it possible to remove the alt account off my switch 2 & add my OG OW account onto my switch 2?

Thank you. :folded_hands:
