Hello! I am very impressed by your work here and have ordered some cheap programmer to attempt some of this myself. 
My programming skills are sub-par and I may not be as able as willing to contribute, though, fair warning. 
I wondered about two things primarily, to start things out. One, is it reasonable to buy a new chip and experiment with that one, using your code as the starting point? By doing this I will keep a spare chip and sleep at night 
Two, I also have an X7 classic I'd like to experiment with, how much of the code would conceivably need to be rewritten to suit the classic's trigger system and solenoid?
Keep up the good work!
