If I understand your question, the speed controller alone won't work with the VPI motor. The Sota system comes with a motor that will fit most VPI motor housings.
The Sota motor is better than the Hursts that VPI uses. It runs with much less vibration and there is no cogging.
IMO, the Sota package is better than the VPI motor with SDS, which I have on my second table.
If you do go with the Sota, I would highly recommend getting the Roadrunner with it (Total Eclipse Package).
