Couldn't I simply power the flybacks primary with the amps output (provided the wattage is sufficient)?

Not really; you need to drive the flyback with its resonant frequency, and
modulate that frequency with the audio.  Efficiency will really suck driven
with straight audio, unless perhaps it's "Easy Listening music for Dogs."
Flyback transformers are not resonant. Using the regular primary coil you need something as 1000 V at the input to get some significant output. Less if you wind another primary coil with less inductance. It's possible to resonate the primary coil with a series capacitor to increase the effective input voltage. Using an amplifier would then be similar to using a half-bridge driver, with far less efficiency and some risk of destroying the amplifier. The amplifier
has to be driven from an AM-modulated signal generator, as said above.
