It might be possible, by carefully pruning the coil, and adjusting the end
plates of the capacitor by bending them in and out. It would depend on the
fixed >capacitors used in the tuned circuit.
Good luck.
It would probably be more trouble than it's worth, since the capacitor will
need to be somewhere intermediate between straight-line frequency and
straight-line capacitance, and which would be designed to work over a
specific, limited range of maximum to minimum frequencies.
Probably better to just do like National did with the HRO and NC-101 series:
make up a tuning chart.
