Lamp recess could be filled in fairly easily. If you have the lens, polish inner surface with release agent or wax. Lay up 3 layers of fiberglass inside. Pop out the formed fiberglass cups & trim to size. Glue in place with flox slurry. Finish off with micro balloon mixture & light bondo as necessary.
This fix would be cheaper than the cost of freight if you did find a pair of tips without the recesses.
