Chris, congrats on a much simpler mechanism.
I'm not sure from the photo how your mechanism works; Does the new vertical spar rock vertically, and is the 1st octave key sprung closed, and not open as usual?
Pressing the octave key pushes the spar up, 3rd finger holds down 2nd Octave, so 1st Octave has to go up. when you raise the 3rd finger the 2nd octave can rise, and this allows the 1st octave to spring closed again. I suppose the springs must be balanced so that 2nd octave spring is weaker than 1st octave.
The only adjustment would be to balance G-fingering and 2nd octave closure.
Truly ingenious!
J.
