[Amps] Sharing 15 and 10M on a single band switch position?

My emerging project amp (a reconstituted Alpha 76A that is missing it's tank circuit) would normally require a 6-position band switch, but the switches I have (one and a spare) are 5-position. I'm thinking of designing the tank circuit to share 15 and 10M on one switch position, by having the PI network designed for around 24 MHz, on the theory I could use it on 21 and 28 MHz. I don't plan operate 24 MHz itself with the amp. Losing a bit of efficiency on 21 or 28 MHz isn't a concern. Anything else I should be concerned with?

Thanks,
