Using Multiple VESCs in Robotics?

Hi, I plan on using multiple VESC controllers for a robotics application. However, it turns out that the CAN bus to communicate between the controllers is too slow (only 1 MBit/s). CAN-FD would be fine, but it doesn't seem to have been implemented. Is there a way to make the controllers communicate at a high data rate (>1 MBit/s)? Thank you!
