A work around to the 4 arms thing would just have it keep you at 2 arms instead of throwing the 4 arms crap again. The Gold Myr TF keeps you at 2 arms despite the fact that they normally have 4, since you aren't born a myr and all. If you're gonna be looking for a work around with the arms you could just do that.
The biggest deterrent to interest is that they're basically 'Asexuals: The race' in a nutshell. They lack the ability to feel sexual pleasure entirely and don't have any sexual organs whatsoever. Tlako modded hers in yes, but she doesn't get any real pleasure out of it, it's just a hole.
So as cute as it'd be the be one, I very much rather not be a sexless birb neuter who's sex drive is deader than the Sahara Desert.
