well, the Pierce oscillator does not give that much freedom, the steady
state loop gain should be Pi (about 3) as the RF Gm = Gmo/pi.
This analysis does not address the important SSB noise gut guaranties
oscillation.
In testing enough a loaded Ql of Qp/2 is best for power matching and
good phase noise.
Too much loading no selectivity, not enough loading too much resonator
insertion loss, far off noise. Life is full of compromises.
