Having seen the spoiler images, I personally think a Two-Face figure is going to look too disgusting for anyone who doesn't already collect horror figures to want to own it. It'll look really out of place on a shelf containing most other high end figures.
I don't think that at all, I think it'll look perfectly in place in a Batman display. It might look off to people who don't understand Batman, but anyone who does won't find it out of place, they'll think it's a badass Batman figure.
