FM receivers are designed to not respond to amplitude variations. CW is
about as pure an example of "information conveyed by variations in
amplitude" as one is likely to find. To cut to the chase, what you
propose won't work.

That being said, one can send Morse in a format receivable on an FM
receiver, but it'll be MCW rather than CW. Feeding a keyed audio
oscillator into an FM transmitter will produce MCW. The caveat here is
it is legal here in the states only from 50.1 to 54 MHz and above 144.1
MHz.

So, If I had a receiver capable of AM reception, then a CW filter would
work?
