There is no way to run a proper IMD without a band stop filter that rejects the 2 tones and a band pass filter for each of the tones.

Absolutely, it's no good unless you can notch out the fundamental tones.

My own notches provide about 40dB rejection, which is just about good enough.

Definitely, but without? notch filters for the original 2-tone signals the tiny-SA will become overloaded. It's own IP3 is about +17 dBm.
