Thanks for the kind words! To encourage this kind of behavior, here's a file that should get you most of what you want. You can specify any number of red D6, D8, D10, yellow D6, D8, D10, green D6, D8, D10, and defense D6's. It does NOT do the bonus stuff.
I didn't 100% vet this, but I think it should be right.

Please let me know how it looks!
EDIT: Quick note - I just looked at your original post and see that ties should go to the attacker. Here they go to the defender. To fix that just take out the +1 I add to the Defender highest die.
