Tweeter removal

Hey all,

I'm thinking about relocating my tweeters to the A-pillar. I'm wondering if there's anything I can use to plug up the holes in the front where the tweeters are placed. I could leave the tweeter trim pieces there, but I think that would just annoy me since it's not actually functional. I know one way is to just get new trim for the doors, but I'm wondering if there might be another suggestion.
