Metal Bonding Questions

I've been following this thread and have a couple questions also.
I am grafting 72 'cuda scoops to a Dart hood, would this work
for this application?
The plan is to cut out the Dart hood, flange the edges and set the 'cuda skin
down in it.
Not having to weld it in would be a lot easier to control warpage,
and I could still fill the seam properly?
