Frequencey Modulation

Hi there just another question about FM radio

i am making this circuit, i have made it before using a coil and capacitor for the modulation however i was wondering if it is possible to use a 555 IC with a calculated frequencey and have it outputing a voltage at a frequencey what would then create the correct frequencey.

My idea:

would my idea work?

You forgot to attach your image.

That FM transmitter project is a simple toy that has its frequency change if anything moves toward its antenna or moves away and as its battery voltage runs down.
High audio frequencies will be missing when an FM radio receives it.

FM radio is at 100MHz.
The max frequency of a 555 is only 0.5MHz so it won't work in an FM transmitter.
