The simplest and easiest way to do this would be to set up a bunch of =
mattes and do it conventionally.  It would still be quite complex, to =
cover all the possibilities, but you could approach it up in a logical =
manner.

If your circles were strong solid colours you might even be able to set =
them up in a precomp with an add blending mode, then key the resulting =
colours to create mattes for the various blending modes you want in your =
main comp.

It would still get fairly complex, and I'd be interested to know why you =
wanted to do this.  I would have thought that blending modes by =
themselves would be able to do what you want.
