Is it possible to mount tweeters somewhere, aesthetically pleasing, that requires no fabrication: drilling, cutting, etcetc?

In an FD.



I know separates are ideal, and they are the same price as the composites I am looking at, but I just don't want to cut into anything, or have speakers protruding in an unsightly manner (that was an awkward sentence lol).
thanks.

 

This is what I did...
