Broadstone .... your question is reasonable but difficult to answer because there are so many variables involved. Ergo the various suggestions above.
What I'm about to say may be a bit heretical, but if you like your ML ESLs, why not fix them and keep them. I don't recall reading that you are experiencing compatibility issues with your MLs and your amp. And to start fiddling with separate components ... oiy. You may take one step forward and two steps back.
As to your concern about metal domed tweeters, I've read many posts that go both ways. Someone mentioned the Revel Salons and Studios. These speakers use beryllium dome tweeters. Same re the higher-end Focals, Paradigms and Ushers. Beryllium is a very light and brittle metal that has a higher resonant frequency than other types of metal tweeters, like aluminum and titanium.
But even these exotics can sound bad if there is system incompatibility with the gear and the room. That's why I suggested that if you're happy, consider sticking with what you have. Just a cheaper and easy alternative option to think about.
Cheers.
