The Jaguar stuff from TI is still available. It is included in the free StellarisWare development kit download. The BDC-COMM source code included in that is useful. The RDK-BDC24 development PDF (google "7870.SW-RDK-BDC24-UG-7243.pdf") is also useful.

I think you'd run into bandwidth issues with the serial bridge with that scheme.
Definitely. It's even a bit much for the 2CAN if we want to preserve some capacity for CAN errors and web dashboard diagnostics. Jaguar firmware wasn't designed with this control scheme in mind.

What looks feasible is to catch power cycles and only reconfigure when necessary. Delaying all the CAN output commands to the end of the periodic code allows us to easily catch changes to Jaguar state. It might not even need a separate VxWorks task.
