If you turned all auto sun off, Would using a mouse on console be cheating? For pharah specifically?

I play on pc and console, and can’t aim pharah on sticks to save my life, but love playing her on a mouse…

I’d love to play from my couch and big screen where my ps4 is set up. If I use the ps4 controller in my left hand and mouse for aim/shoot, with auto aim off, would you consider that cheating? Like “ximing” ?
