If I were you, I would be making a workbench as well. Using your hood I don't think should qualify as a workbench. lol. But the bumper should look sweet when its done. Some of the best looking bumpers, imo, are the simple ones.
haha i got about 20 square feet of workbench in my garage, i was just too lazy to walk up to the other end (garage is 44' long) and i just threw it up on the hood to slap on the factory mounts to see how they worked out
