Different idea for legacy badge / change name on legacy badge

I think it would be nice to have an option to keep the legacy badge, but name it "legacy user" instead of displaying your old name. I recently got back into my old account, and the name was changed to some weird user I don't want any more but of course couldn't change it before the username rollout. I assume it will become a common issue to want the legacy badge, but not the name tied to it, especially since so many are changing their usernames as their old ones are unavailable.

I think eventually, once all the names are fully rolled out, there should be a nicer more general legacy user badge similar to the early supporter in a way. Or at least an option to change your legacy user name for a period of time after the name system is completed.
