Anyone building DRV8350 based VESC?

I have been interested in using VESC for low cost e-bike projects for quite some time, but the 60V limit has always been a major problem. I see that TI now has the new 100V DRV8350 shipping and it seems rather similar to the DRV8301 VESC uses. The DRV8350 comes in 40-Pin WQFN package rather than the 8301's 56-Pin HTSSOP package so it's not quite a drop in replacement, but it seems close. Price wise, the DRV8350 and DRV8301 are nearly the same on digikey.

So a higher voltage VESC would need a different layout for the driver ship, higher voltage capacitors and MOSFETs. What else?

Has anyone already started on this? I suspect the market for VESC based e-bike products would be similar or larger than skateboards.

We have been looking into it, and we currently work on designing some new hardware with prototypes coming soon. There are plans for a 75V or 100V version of the VESC6 (with lower current limits and maybe low side shunts) in the near future.
