oooohhhh.... I LIKE that idea and I'm jealous that I didn't think of it first.  :-)

Thanks for mentioning that!

It occurred to me that in this circuit, the 2 capacitors could maybe even be replaced by a 2-gang variable of low capacitance. -Hue   >I remember encountering that CMOS design but if I recall correctly the text that was with it indicated C1 & C2 & Rs had to be selected for the xtal range to be used.  https://www.electronics-tutorials.ws/wp-content/uploads/2018/05/oscillator-osc32a.gif    I haven't given that one a breadboard try yet.
