71-73 sport mirrors convert dr's-side remote -to- manual w/ pass-side internal hdwe?

brand new to forum - was referred by wccc. hopefully this is the right place to post - if not pls lemme know & i’ll redo it all.
i really like 71-73 flat mount base cougar sport mirrors & wanna retrofit to 63 failane 500 sports coupe i’m restoring as a restomod.
i want to convert / retrofit dr’s-side remote mirror to manually operated as have custom door panels & do not want to cut into them.
does anyone know if i can replace the remote hdwe in the dr’s-side mirror assy w/ the pass-side manually operated hdwe -and- it will still work?
