It is a good idea.

Lol, I won't let the idea die!
For the grille block, the general consensus (as in no solid reporting either way) is that an exterior block is more effective in improving MPG, either through drag reduction or speed in which the engine heats up, or both.
If you don't mind the work, one can make a quality product. One can be more frugal/lazy, and get polycarbonate board and create it for the shape and cleanly install, or make it out of fiberglass*. Surely it could be made other ways, on my Mustang GT front fascia and my Insight front fascia I used Great Foam to fill in the openings (they were/are recessed) and will be completing that project when 100% grille block it too much.
*The knowledge here helped teach me to fiberglass, and encourage me to learn. It's extremely easy by using solid sheets and pieces- I have never used the fluff.
