If you like the name, keep it. I'm planning on keeping my male name and it's an obviously male name, but I think it makes a beautiful, unique female name too.
I guess it also depends what your end goal is. If you're going for stealth, then perhaps an unequivocally-female name is a better option, just so that it's one less thing that might give you away. If, like me, you're gonna be obviously trans, then there's absolutely no reason you can't stick with whatever name you choose: it's hardly the weirdest thing about our genders...
