As theories go, Robin becoming Regina's Magic Mirror is not as bad as some, but I'm not a fan of it, either.

Still, There is something to be said for Robin, who always found a way to see the better parts of Regina even when he disagreed with her, becoming the Mirror that helps her see her better qualities and focus on those rather than the negative ones. I won't discount that possibility.

Besides, as we saw in Season 4, Regina always needs her mirror. XD
