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: https://wireless.murata.com/RFM/data/px1002.pdf
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.
