You could always use pop rivets.

The company I work for sells ACM (Aluminum Composite Material) in 3mm and 4mm thickness that you could drill and pop rivet. You could even apply vinyl sheeting to the outside with a UV overcoat or just spray paint it.

It looks like the male end of the snap? What ever it is called, it attached using a pop rivet and then the end on the fabric or cover is installed using a specific tool.

I have a LJ top for sale that you might make work.

Fwiw right now, it looks like industrial Velcro is the way to go for what I want. Same stuff used on fire truck tarps. Not waterproof, but I can work around that.

Yep, Velcro for the win.  I use a lot of the industrial Velcro from home improvement stores (for various projects), which is very strong, but which has issues with the glue lasting in hot temperatures.  I would sew the Velcro loop side to the canvas top, which may require an industrial strength sewing machine, or to outsource the activity to an upholstery shop.  Rivets and glue work well for adhering the hook side material to the metal.  My truck tonneau cover, which uses Velcro along the sides, is designed to keep water out by having the edge at an angle (about 30 degrees).

That's exactly what I was going to do. This upholstery shop will make me a 4x3 top for $50. I'm going to have it sewn to the top and screwed to the roof with a loop of the top corners to yank it up by. I think it should turn out nicely. I thought about building something around the sunroof, but I'm not sure what I would do.
