many years ago I looked at spice to do software simulation of circuit behavior . It 's a bit of overkill for this but there is open source software available that can model a circuit to see what components would work. It just might be a fun experiment. I am 25 years removed from this work but it's good to get back into the flow. BTW, the circuit I saw some time ago belonged to Ron, so it went beyond the napkin note phase as it was online somewhere.
