Interesting thoughts. I may look into the grille block from the back.
Electric fan will happen at some point for general economy and horsepower reasons. I do have a clutch fan so like you said it's not a big priority.
Looking underneath, there's a nice ridge created by the seam of the gas tank (it's mounted vertically right behind the rear axle) that could be the front of a rear bellypan, ending at the rear bumper.
It's 6 (?) screws to yank the grill so experimenting with that would be relatively easy.
There is a factory (for Police models) front air dam that I'm going to find or try to duplicate. Roughly 3 inches vertically and about the width of the grill. It mounts on the radiator core support (about halfway to the front of the wheelwell) but I'm thinking mounting it from the bumper and making it wider would be more effective. Maybe even something like the Home Depot garden border stuff the full width and profile (ie wrapping around) of the bumper.
