Adding sensors to Kakute H7

Hello, dear community! I am trying to incorporate the sensor module (which AFAIK works with I2C) from the Cube Orange into a Kakute H7 board. I would also like to enable a CAN port on this board to connect a Here 3 GPS module.
I think I should be able to address the sensors by specifying pins in the hwdef.dat file. But I’m not sure about adding CAN support. Any input/validation on my methodology would be welcome.
