I'd just weld it, but that's me personally. My DJ has several very ugly welds, and one of the suspension welds is the very first one I ever did with a wire feed
Whacked the **** out of it with a hand sledge to be sure it would hold, and no worries. It's dog ugly, but it's mine
You can bead both sides and then take an angle grinder to the "show" side... I've had pretty decent luck doing that.
Just remember that sheet metal goes FAST... biggest worry is putting a hole in it, but even "bad" welds in sheet metal get a pretty good grip from what I've seen.
