I think you're making the H pattern no lift shift more complicated than it needs to be. For upshifting, it is very simple. Cut the engine output while the clutch is down. To shift, you just keep your throttle wide open and operate the clutch and shifter as per normal. It works very smoothly. No timer used, no dog gears needed. For downshifting, blip the throttle manually (well, there's no other way with a manual throttle body).
