Remember the AM modulation concept, you have say a 100W carrier. To obtain in an ideal circuit 100% modulation of the carrier you need a modulator of 100W. You therefore in ideal circuit, obtain a carrier that just about approaches (0) (otherwise distortion) signal carrier valley, to a 200W carrier peak.
In the receiver the carrier is discarded (filtered out) and only the modulation component is processed and amplified for recovery. Now in your circuit where is the detection portion? In other-words you will via skin effect swamp you output (load with a combination of both the modulation and the RF, n nothing is present to separate it from the load. Indeed any lower frequency action on the load side would be reduced in reflection back to the driver (depending on the caps and coils in series), yet this will not work as shown, at least not what you want from it.
Here is a thought to process. In AM modulation, just how did the old crystal radio develop enough audio recovery from a uV RF signal? No it was not because the user had miles of antenna.
Anyway just my two cents for the day. Good Luck with the venture.
