...reduce weight, decrease rolling resistance, and reduce the time it takes for your engine to heat up to normal operating temps will help. Aerodynamic improvements will help but are less dominant at those speeds.
Agree

For a short commute, you could remove the front passenger seat to get rid of 35 or so lbs.

In my experience with the exact gearing you will get from your VX trans, unfortunately, it is not better for stop and go driving. It is best at 55-65 mph freeway cruise. BUT, the HX's lean burn will work way down at 25 mph. And I have found that my DX loves the 4th gear down to 25mph and fifth gear way down to 35mph. I get great instant mpg numbers (like 70 or 80+ mpg) and a lean AFR in my DX at those speeds in those gears. So depending on the specifics of your route, you might perfect some cool low speed lean burn cruising in 4th and 5th. That would be quite cool.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. 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.
