Hey since this is the Electronics for Retards thread can I replace this IF transformer with a differential amplifier?

IF cans are hard to find and expensive compared to a few decades ago and I hate winding my own transformers. I still want good isolation between the LO and IF. Diff amp is high impedance and it allows me to impedance match easily. Throw a buffer on the output and throw a 50 ohm resistor on the output. Easy 50 ohm output impedance.
