pleaqse think about the fact, that from the antenna input ot the first mixetr there is a lowpass fitler with a cut off at about 30 MHz, so receiving 50 MHz at whatever IF would need to circumverent theis filter!

Datasheet for 86.85mhz SAW filter:
Here in the US, our FM broadcast band starts at 87.9mhz,
at which point that SAW has 60 or 70dB of attenuation.
However, if you are unlucky, there might be a local channel 6 broadcast TV station
dumping on 82-88mhz, in which case some shielding would be in order.
