I like way you think.
However in that picture, it isn't tucked in. Shield is there, just black. Still has trailer hitch on it which right in the way of moving bumper in.

The bumper bolts right to rear horns so those would need to cut back and then the supports on either side need to be cut down.
Rods can be remade easy enuf with smaller, tighter radius.
Pretty sure bumper will hit 1/4s before you get it the 2" or to be able to lose the gravel shield.
I say measure it out and do it if it will work.
