2023 Onward HP - Navitas Conversion

I have a 2023 lifted Onward HP, lead acid, and exploring my options for more speed. There seems to be only 3 available:
1) 8:1 gears change out
2) Wait for Navitas to break the Club car HP code and come out with a new controller motor combo
3) Swap harness for the old IQ harness and install the current Navitas DC to AC conversion

I'm leaning towards options 1 and 2, but interested if anyone has any detailed experience with what is essentially a AC - DC - AC conversion. More specifically, what are the limitations with the harness swap? Will I lose any functionality on the cart such as the factory reducer to some other unintended consequence?

Thanks,
 
1) The factory AC carts use 16.99:1 gears as opposed to 12.3:1 in DC carts, changing to common stock gears/axle would give plenty of boost
2) The factory AC carts have everything integrated through the VCM and functions over CAN so not going to happen anytime soon if ever. So you would need to
3) Rip out everything and start from scratch. Not as hard as you would think, these things are built like legos. Get the Main Harness and IP harness for DC, Navitas AC kit. If you have the new style APPS you also will need to convert to MCOR unless Navitas has figured that part out now. Remember you still have torque gears which will lower the maximum speed. You may also need the DC lighting harnesses as well because they all run on the VCM too, not sure if you could make the VCM function without the controller (likely not) or if you will need to go analog.
 
@Golf Cart Wizard , very informative, Thank you. I wasn't aware that the factory AC carts came with 16.99:1 gearing. Do you think a 8:1 swap would absolutely kill torque? Alternatively, would using 12.3:1 sufficiently increase top speed while maintaining a decent torque curve?
Would this predictive math match reality? 8:1 = 38MPH @ 50% less torque 12:1 = ~26MPH @ 30% less torque
In addition to a 12:1 swap, I could maybe change the lifted and tire settings to non-lifted on 12" tires and squeeze more RPM and see a 30-35 MPH with minimal torque loss at the gears.
Mostly thinking out loud here... open to feedback if any of this logic is faulty.
