I'd just configure the relays in the uBitx for 80m (the 80m LPF will pass 160m too),
then add an external LPF when using the uBitx for 160m.
If you have a separate 160m antenna, there is no loss in convenience.

Only another lpf and code changes required? Is there a spare uc pin to control some relays?
