Nice, but why not just use two Jumpers or a DPDT switch rather than add
additional silicon?
My preference with the more recent PIC's is to use PPS to assign the USART
to those pins.
I then use the PICKit as a terminal for debugging as well as a Programmer.
The serial interface may even have a use in the target application.
Have the serial interface use the same pin assignments as the ICSP and you
have a nice 'Plug and Play' programming/debugging/communications port.
