i agree with surfoverb. i don't know that the fralins will be something you will be that happy with considering what you have described so far.
i *love* fralins, i have blues specials in neck and bridge of all my teles except for one that has a fralin twangmaster in the neck and my latest tele which i just got last week (so no time to muck it up yet
) - so it would be easy for me to just say, "get em, you'll love them". but they are still bright. if you don't like stock tele brightness i don't know that fralins will help you too much.
I would describe the fralin BSs as just as bright as stock, but with a lot more character, a little more mids, and a great break up at 8-10 if you have your amp set up right.
