I feel like if you don't really like the look of your Guardian's look, you should be able to redesign your Character at the tower, for a price like, I dunno, 10K glimmer or 10 legendary shards?

If Ada-1 has been downgraded from weapon master to fashion crafter, give her an option to redo your appearance, once per season, additional times costs silver. Heck, same thing for a Bungie name change. First name change is free, $5-$10 for additional changes.
