Design Suggestion for Duty Cycle Extender

Hello guys, I am looking for a better design suggestion for an 80MHz suty cycle extender and phase shifter. The one that was suggested to me was an RC circuit with a shotkey diode around the R to charge the C quickly so the circuit will slowly discharge through R, effectively increasing the duty cycle. This would be between two High Speed comparators to produce an interface to a square wave.

 

And then we would be picking the signal from a series of high speed logic gates to generate a transition delat of the signal for the phase shift. All of this would run on 5V.

 

Anybody have any better ideas?
