Spring of 2018 after Whedon's Batgirl put on the backburner:
WB was finalizing 2 different Birds of Prey scripts and Batgirl was rumored as a constant I saw the best fan art depiction of her that I think cements Jane Levy in the role just wanted to post here as there's been so much discussed since then and I think the best option has been laid out already:

The character in "Don't Breath" horror film I remember her from most but yeah she's the perfect choice for Batgirl.
There's a couple other fan manip photos of Jane Levy in the role posted in June 2018 here:

They're rougher photo manip jobs for both a fan casted Huntress and Black Canary as well as a separate poster featuring Batgirl too. If anything, I don't think the big haired look should be gone for with Batgirl anyway from a characterization standpoint as it just doesn't seem to gel.
The actress is on the shorter side at 5'2" but movie magic wise that doesn't matter. She's athletic looking and can easily do the part.
