Any mods to decouple racial mechanics from appearances?

I'd just like to be able to decide my character's race for RP and/or aesthetic reasons rather than mechanical ones. If RP says the character should be a deep gnome, but mechanics say an elf would be far superior, I'll basically have to just scrap the character idea because I'll never be happy with it regardless of which I choose.

Is there any mod that separates the two? All I can find with Google are people asking for the same thing. One post said a cheat scroll/ring mod would do it, but I checked the page and there's nothing on it about doing this, only a bunch of other things that I have no interest in whatsoever as I don't like mods that change the game's balance.

Apparently, Appearance Edit Enhanced used to do this, but it no longer works, at least not for long. It'll change the race without changing the mechanics of the race, but eventually the game will notice and update the mechanics to match the appearance.
