"...I would suggest that you consider using a Reed relay or similar fast acting relay to short circuit the external preamp's input during transmit periods..."
Take a look at the Omron signal relay, Mouser part number 653-G6A-274P40-DC12. These relays operate in 3ms typical, 5ms max. I use them in my ALS-600 QSK conversion and they work great.
