I suppose you could weld in egt threated weld-o-lets for the probes and install the probes only when tuning the engine and perhaps at annual time to check the mixture distribution and injector differential wear. You can have them plugged with a same size plug as the probe threads the rest of the time. Probably the best solution. Then just use the one TOT after the turbine for egt monitoring.....and overtemp monitoring of the turbine.
