You can switch spark plug wire connections between 1 and 4, and between 2 and 3, but that's it.
Per the FSM, the firing order for the DOHC engine is 1-2-4-3.

Sees, I found your other posting from Jan 2012.  If you go with that firing order, the bike will essentially be running on 2 cylinders.  It will be low on RPM, and not accelerate well, but it will sort of run.

I remember reading somewhere that these engines will actually run if you spin the crank in reverse fast enough.  It won't run well, but it _will_ stumble along.
