ROM Hack Fire Emblem awakening playable masked marth (lucina)

[Rumslug]

Hi everyone, just got into hacking fire emblem awakening (I know it's late) but I've been looking for a while now on is there a way to play as masked marth/lucina. I already tried a save editor and that was just to make duplicate copies and change hair colors. I tried some cheats but I can't find a way to make lucina wear her butterfly mask. I was planning on making a duplicate lucina and changing that one to masked marth with the artwork swap, pallet swap and everything. I know this might seem a little corny but if someone could assist, much will be appreciated.
