you wana know what i think would make a super beefy and great front bumper would be one of your front bumpers with a big grill gaurd built in like the older bolt on grill gaurds you use to get for the front bumpers.
pic 4-5 of your stuff.
pic 1-2-3 is a fisher plow summer bumper center this thing is a tank.
combine the 2 and i would mabye consider buying one of them. take the main bumper like you have made. then give it the grill gaurd support like i have bolted on my plow frame on the top half. i my self think it would be sick.
