It's not likely we will get a good female Robin anytime soon. The current Robin, Damien, is the actually birthson of Bruce Wayne (from the graphic novel - 'Son of the Demon') and is quite a little brat. I do like him however.
I guess if you are looking for a female 'Robin' you can look to Stepanie, the former Spoiler, Robin and current Batgirl. She is young but works more solo than with the Batman.
The closest thing we ever had to a female Robin comes from 'The Return of the Dark Knight' by Frank Miller. His Robin, Casey fought crime with a sling shot which was a cool weapon to use.
Besides those little pixie shoes just look better on her than on a guy.
