@glyph Long story kept long: Maybe, but most likely not noticeably enough. Digging into the future motions patents gives an insight on how the OW + vs V1 motors are built.
OW+ being about 2 pounds lighter, and having 5 Celcius better temperature performance at the same wattage, (simulations were done at 500W for both).
This increased temperature conductivity is probably how they pulled off using the same engine at 750 W instead of 500W, (remember that the V1 does have ~1500W momentary power, [ultimatley wattage is just how much Voltage and Amps you run through the motor]).
Anyway, getting back to the subject at hand. The improved thermal efficiency has probably been maxed out with the OW +, assuming all equal except the battery pack, we could see momentary increases in torque during cold starts, but as soon as the motor is up to temperature, I believe that will be the limiting factor.
The Battery chemistry is also different, NMC have a lower specific power than LiFeP04, but higher energy density. (Like running a small hose at high pressure, instead of a big hose at low pressure) On the other hand NMC (small hose high pressure, has a larger water tank. )
Issue 2: also by digging through the patents.
There are hints of the foot pads acting as an approximate weight sensor, which tunes torque(amps) feed to the users weight. This could give the rider a preliminary sense of confidence, as the board will compensate for a rider with more... em.. potential energy (weight) , but again, once the temps get maxed out, the board will save your investment from itself, and let you take the hit.
