No. Tank circuits (changing in steps) are wideband. There is some sense to connect spectrum analyser to RX tank circuit only. Oscilloscope will show you only mess of frequencies. Replacing LED-s by scope is nonsense.
There are other way if you wish to select / tune to only one RX frequency. You do not need to ad scope or f-meter.
