Well, maybe the right tree but just barking in the wrong direction? I'd be more inclined to just replace the speakers completely vs. trying to add in tweeters. I don't know the size of your Conn speakers but there's a ton of speakers available that have built in tweeters, in fact some are 2 and 3 way speakers. Yes, the ones you find are likely to be more for automotive type use, but they're out there in abundance in and in various sizes. I'd also check places like Parts Express, they've got a huge selection of speakers, that or try the local Best Buy and see what they have. This way you'd have a matching driver / tweeter combination that's designed to work together, there's no telling the outcome if you try adding tweeters. The only thing you'd need to verify is what ohm speakers you'd need and I'd think the sound outcome would be much better.
