A year ago I implemented a basic version of Blend If using a Custom Tool. The maths is pretty simple and I doubt mine is using the same maths as Photoshop - theirs is probably more sophisticated. But this might get you started if this is a feature you need.
The code is provided and described in this post on the We Suck Less forum.
