The front of the rudder is easy to take off, its hollow back to the support for the hinges. A sharp exacto, hot knife, or friction wheel on the dremel will get you started. A sanding block and a new leading edge will finish.
I am going your route Brian, the stern post hinge points are too easy to crush with the mechanical advantage of the exposed part of the hinge. I figured out the same angle issue as you did and also that I can sand down the TE of the fin so that the rudder counter balance will move forward realign with the fin.
Feel much better with that set up.
Regards.
P.S. That hot knife (Foam cutter) is great for this skin and foam material. Just be careful where you put the old blade when you swap in a new blade, while everything is still hot -- don't ask :-(
