Thanks Pete. Yeah, those rings came with the tweeters. They're actually flushish mounted. Meaning I cut an egg shaped hole out of the top of the door panel. The tweets sit in and there's a bracket that screws in to keep it in place. From there the wiring drops down to behind the woofer and through the panel to the cross-over.

I think that plan of yours would work well actually. I've seen some tweeters that just mount with small screws when surface mounted. So if you didn't want to go through all the hassel that you just described, you could take a piece of sheet AL, cut it to fit inside that trim piece to give it the support that it needs. Just a thought. Although, I like your idea better. I think it would look much better, much more substantial.
