advice - Jeep under bumper something?

So thinking about my wrangler (the box on wheels) and aero mods. I'm not sure anything will really make a difference unless I first get rid of the safari rack on top, but I use that for hauling stuff all summer long!

Help...
So I'm thinking about moving the license plate up in front of the grill, and then putting a big front air deflector below the bumper to keep the air from going under the rough jeep underbody. I'll make it removable, since I frequently drive in 1' deep snow in the summer. The bumper has nice bolt holes already in, so I can overlap the bumper and bolt right in!

Also what material to use? I was thinking heavy metal flashing I can just cut and it wraps around the side bumper curved thing too.

Or... don't do the bumper thing and
should I try to smooth the underbody with plates? That seems less removable, and also may be a problem in deep snow - I'll tear them off with deep snow 4 wheeling. I'm also less excited about figuring out how to do the under body work. less obvious where to bolt stuff.

Thoughts on my bumper chin thing? Please!

Engine skid and a tummy tuck would help on the under belly

For the bumper to fender area, you might want to see if you can score a set of the export milk jugs. They cover that gap pretty well

For an underdeflector thing, I fabbed up this for mine

Its going to get the acid test over the next couple of days, need to drive from the Bay Area to LA so its going to see a good few hundred miles of highway.

You must live in the southern hemisphere or the mountains!

I think your idea will work; if you want it to be pretty tough you can get sheet metal from a heating and air conditioning company for ~$1 per square foot. It's pretty tough to rip that off.
