Target is the 45 mpg (which is really 42-43 mpg) at 65 mph.
Under belly was an option.
Lower air dam with side skirts to channel flow away from getting under the sides and also to channel flow away from the rear tires.
Moon covers and mirror deletion should be fairly easy also.
Heck, if it takes all these mods to reach my goal, and hopefully then some, then so be it.

B,I noodled your numbers and here's what I got.
To go from 38,to 45 mpg at a constant 65 mph cruise is an 18.42 % delta-mpg.
Between 55 mph and 70 mph,I guestimate that any 10 % drag reduction will net you a 5.5 % mpg increase.
To get the 18.42 % would require a drag reduction of 33.5 %,or,Cd 0.186.
So your target is 0.186,close to the 1996 GM EV-1.
There's no physical barrier to get you there,although it will require a pretty comprehensive mod list.
Do the nose mods and lets see where you end up,but be thinking about the AeroCivic.
