Good... I spoke to my dad about the brake balance. We figured we would try and plum in an original mini break limiting valve and see what that does in terms of break balance, as you don't go much above 30mph on the test day, so brake balance can be properly fiddled with once its registered because as you said, adjustable proportioning valves are strictly prohibited :/ As for the number plate, that's one less thing to worry about
I look forward to seeing the drawings! I'm going to try and get more work done this weekend in terms of preparing everything else, so that once the system is fabbed on then i can start her up and test her vocal chords

haha.
