    In older days, this might not have been too big a challenge. With varactor diode tuning in the front end, life could be harder. If you can show us a schematic of your receiver front end, we can make a guess about how the tuning frequency might get changed upward.

    An FM radio is wideband.
    Anything up that high is either AM or narrow band FM.
