Welcome!

You didn't tell us where you are......and the riding geography has a good bit to do with it .......and this doesn't answer your question.....BUT:

65-70 is still doable on the flat without a significant headwind with a 16T sprocket, but it takes a while to achieve 70 and you can't maintain that over anything but the slightest hill. It does, however, allow you to maintain 60-65 under adverse conditions (headwind or uphill) in 4th for short stretches. This is my experience with a 180 lb. rider and a large windshield.

I suspect the answer to your question is: NO. Changing the front is so quick and easy I doubt anybody has gone the other route. Is there a reason that you don't want to try that first ??
