Hot Rods Filled and Peaked 32 grill shell

So I picked up an old beat up aftermarket grill shell and I thought I would fill the radiator neck hole and form a peak in it like the old days. I've filled the hole and thought I would see if anyone had ideas on the peaking part. I did one many years ago and just molded it to a peak with bondo. Got any other ideas out there on differents ways to accomplish this?

 

peak a piece of metal and weld it in
