You can boost the tire pressure to the max listed on the tire sidewall.
You can slow down your max speed. I bet that cruising at 55 MPH in top gear will put you well over the 50 MPG mark, in fact.

I think that you may be right. There were moments when I'd encountered longer stretches on the freeway at 55MPH that didn't put as much stress on the gas needle. It made me think that the people who claim to achieve 55MPG at 60-70MPH were just blowing smoke.
What about performing a valve adjustment, or using Amsoil 5w30, or even flushing & filling the cooling system with Honda coolant? These are other suggestions that I have encountered here and there from various sites.
