It would take some fabrication; but it should work.
What you want to do, is have a Warn winch plate attached to the underside of the cross-bar, behind the bumper. This cross-bar is not strong enough to support the loads a winch can create. Have a pair of steel plates made, with 6 holes, to match the fastener pattern where the bumper attaches to the frame. Sandwich each of these plates between the bumper and frame, and bolt it back together.
Now, fabricate the necessary structure to connect the Warn winch plate, to these two frame-plates. You should be able to make all the parts from flat, 1/4" steel plate material. Use cardboard to mock up the pieces, cut out the steel, grind and file to fit all the parts, then have a welder bring it all together.
This should put the winch just behind the lower grill, in the bumper. You can also fabricate any necessary pieces to hold the farelead out front. This can take some heavy side loads too, so don't skimp on this part either.
