yep get crafty. get ahold of a pile off really nice sturdy cardboard from a business etc. then start building a badass cardboard bumper piece by piece with tape. After you are satisfied, carefully remove all the tape/pieces and lable them so you know what they are and where they go.
Then just trace all your pieces out on plate and start cutting. Then tack them all into place,fully weld,grind,paint,enjoy...feel awesome
