That's a neat concept.
Put a little more work into the execution and it would be pretty BA.
If it were me, I'd bend up a brass surround that matched the grill impression and then braze the shells from the back into it in nice straight lines. Lop the shells off on a band saw once they're all brazed in so it fits neatly into the grill opening. Probably end up being about 1/2" thick. Then, braze a couple posts on the back and bolt it in the stock location.
If you want to get super fancy with it you can make it like an OEM domed emblem with that clear epoxy they use to seal up the tops of wooden tables with badges and what not buried in it.
Guaranteed people will ask you where you bought it.....you can smile and say "one of a kind, I shot it myself".
