Hell to tha yeah, you can change your footing! It'll be harder than bustin' a face-plant intentionaly but IT CAN be done. To help you do this I'd suggest you tighten your trucks. But I have a question: If it ain't broke why fix it? Many skaters of renown were regular footed: Adlof Hitler himself was an avid regular footed dude and so was Al Capone... Jesus and Buddah were goofy-footed though... so I guess it depends who you choose to emulate.
