Kinn, the revels would match your aesthetix goal and are pretty good speakers. I would not say the are the same as the active ATC's higher models. Another consideration would be the Wilson speakers, much closer to ATC in my experience in many ways. You could go with some silver Sophias or W/P (but not sure if you like the look, I do).
Of course if you want to stretch your budget you will get more into both performance and cosmetics. But your statement that they need to sound like ATC take a lot of contenders out, like MBL for example. They look like a piece of art to some, very industrial and interesting - many people may not even guess they are speakers.
As for Martin Logans. . . as long as you can still get the replacement panels from ML (which I would automatically do for any ML speaker that is 8 years old or more), I wouldn't worry about that too much. Just remember, anytime you buy an ML speaker and the seller doesn't have a receipt for new panels from the last few years, you really need to expect to replace them yourself (easy to do). Sure 8 year old MLs may still sound decent, but your mind will change once you put in new panels and run em for about 100 hours. You will realize the 8+ year old panels have lost their "magic".
