My favourite version of Harley Quinn is actually Harley from the White Knight continuity. It seems like it's the only modern take on Harley to actually remember her own agency, her own intellect (she is a doctor after all), and take her seriously. Sadly it doesn't look like anyone is chomping at the bit to make a White Knight Harley figure,
so I made my own. I took the McFarlane BTAS Harley body, gave her the Jim Gordon Batman holster, and a Suicide Squad Harley head... but it didn't sit right. That head... it's too... well... indicative of a version of the character I don't care for.
Thankfully an eBay seller makes a custom White Knight Harley head, and after hemming and hawing decided to bite that bullet.
I'd still love an official White Knight Harley figure... but if they never made one well... this will do just fine for me
