You also give up most of the usefulness of CAN while doubling your number of control system connections.

Forgive me, but I don't know enough about CAN to see where $20 to $30 came from. I was looking up general-purpose CAN controllers and microcontrollers and found options in the $1-3 range, and PCBs should only cost $1-2 tops. What would drive up the cost?

It's not a good idea.

That's pretty fair. But if you could do it for cheap or wanted to try out CAN in general, a cheap converter would be useful. Plus, it would be easy to go from converter to SRX without changing much code.
