I think I'll have to try a tank in 4th gear at 55 and only use 5th for freeway speeds. Should be about 2300 rpm for both gear ranges.

We'll see.
A better test would be to use your FE gauge and cruise in each gear along the same stretch of road repeatedly in one session. Hold steady throttle, set up a camera to hands-free record an instant FE readout. I did this once with my Civic to explore this exact question and found that the higher gears were much better, even when they gave much taller gearing than my stock set up (I swapped my transmission). My 4th gear was equivalent to my old, stock 5th gear set up. But my new taller 5th gear was much better anyway.

Test it. See what you get. Post it here. I'd love to see.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
