how to help my matrix part 2 (front end)

[Weather Spotter]

After looking at the front end of my car:




And looking at the aero civic's front end, I might want to do something similar.

Ground rules:
1. Must be un doable.
2. Must not damage the stock bumper.
3. Should look somewhat well done (not bumpy, patched, or lots of screws).
4. Must have hood release access.

I am looking for ideas on shape and mount points.
Should I deflect air around the sides or top? If sides I might round out the front (curve in from the sides), have a flat bottom and slope the top down.
How far out should I make it?

...3-inch height garage-door seal as "spoiler" below the bumper.

...use pop-rivets and washers to mount unto existing facia/bumper material.

I might do that, but I have a partial belly pan, so what will it gain me? Besides, the snow we get here makes the current belly pan act as a snow plow several times a winter.
