Looks interesting, like Forkenswift goes pick-up.

You will need higher voltages for the motor and VFD. The motor will run much better on 240 or 480.
This also will reduce you component sizes due to lower amps. Problem is the DC bus voltage on a 480 VFD is around 670VDC !! Most wire is only rated for 600V, but going to 1000V MTW is cheaper than going to larger diameter cables. JUST BE CAREFULL !! High voltage DC doesn't play and will kill you quickly.
Going with 240VAC will drop your bus to 338vdc, much more manageable but at twice the amps to deal with.
Either way, 96VDC isn't going to cut it. 60 some VAC motors don't really exist. A 120V motor will run on it, but will have very low torque.

I look forward to this build.

I can't understand why my MPG's are so low..........
