Your absolutely right, however, i looked into the two switch flyback for a single stage PFC LED driver, and the fact that the two switch flyback shovels energy back to the input when v(referred to primary) is greater than vin means that its not suitable...damn!
As you know, the single stage flyback PFC input bus goes up and down from zero volts.
Unless there is some way round this...hmmm

The flyback energy will distribute very well without blowing anything up.
It can feed both the bulk input capacitor (via the clamp diodes) or the output capacitor (via the rectifier).
