You could split C2 (2x220p) and use a diode with A at the split point and
K at the pic port, and another from gnd (A on gnd K on split point). This
should increase the separation between tx and rx (superregen) modes but
may quench the oscillator in tx mode if Q1 does not have enough gain.

As you said, there are other ways to do it beyond this level of
complexity.
