Perhaps if you explained the intended application/system in detail, there maybe a alternative path to a viable solution.
You also should be aware that the typical wiper resistance is 75Ω, however it can be as high as 300Ω for the MCP4162.
Reference the table below:
Perhaps a system driver issue.
What OS is the computer system running? What revision is the FTDI driver? What version of Python? What version of the USB API?

As Frank indicated the only way to be certain, is to measure the separated drain terminals, however I suspect they are internally connected to provide an adequate path for the Peak Output Current of 6A in the smaller packages. You might also notice the TO-220-5 package only provide one OUT...
You might want to take a look at latest CAN protocol implementations. About five years ago I utilized a CAN implementation over Bluetooth, I realize BT does not offer the throughput need to your specifications, however I seem to remember coming across CAN protocol implementations over other...
Re: pic 18f26k40 bootloader

COLLECT_GCC=gcc
mine
COLLECT_GCC=C:\MinGW\bin\gcc
Although, I doubt that is the issue. What is the specific...
