I'd urge you to keep the same final drive setup - i.e. same position of the front sprocket as before.
It works well with the allowed movement of the swingarm in the Honda design - don't make it tougher on yourself than it need be.
An earlier EV m/c conversion that I've been reading about here on ecomodder, ran into a fair bit of trouble by completely changing the final drive lay-out (using rollers and pulleys etc.).
The load on those parts is very high, and with the high torque of an electric engine, it will possibly be even higher and also very instantaneous the moment you twist the throttle.
I don't want to (re)design your bike conversion, but make full use of the existing engine mounts to mount a very sturdy yet
simple drivetrain.
The output shaft of the Honda gearbox (any bike gearbox) is very sturdy, and very much rock solid, ultimately being bolted to the engine bolts.
You want your design to be equally sturdy.
