I can see that they could have a little sister/big sister relationship.
I think it's fine that Harley can interact with another character other than the joker, so she can show different sides of herself. Same with Ivy. She's the seductress using her plant powers, but it's fun to see her like someone else and give them advice.
But romance between them doesn't work. Harley only has eyes for Joker, and Ivy isn't interested in a relationship.
Harley being in a lesbian relationship and leaving the joker to be a badass grrrl boss is such a vapid attempt at creating a powerful female character.
