You said there is about 1/2 inch between the double walls of the lid. The drill bit looked longer than that. Did you drill through both walls? Did the new rivets go through both walls? A shot of the under side of the lid when completed would have been nice.
If you will drill new holes you may be able to use screws but using the same holes, screws won't hold , and second the material is not thick enough to hold screws

The rivet goes through one wall and hole is through one wall only. You don't see the rivet on the other side.
Why not just use sheet metal screws instead of rivets?

What size stainless steel rivets did you use?
You deaf? Maybe have the volume down? @@jonathandelisle531
