Try a receiver with decent IF filters. Unfortunately, this might be
hard to do in this day and age, but at one time companies
were using crystal filters in the IF stages that offered some
decent adjacent channel rejection.

I should add other than phased stacked antennas to null
the unwanted station, there is really no practical filter you
can use to notch an adjacent FM channel. A custom
crystal filter might do it, but that's many hundreds of
dollars. It's far easier and cheaper to do this sort of
filtering at the first IF. It might be easier to retrofit the
receiver with a good IF filter as compared to trying to
notch the undesired signal or bandpass the desired
signals at the operating frequencies.
