I think Steve's right in that one of the of 3 of 85, 100, and 135 would probably need to go. Which one would depend on what you like to shoot the most. It'd make sense to keep the macro and sell whichever one you use least of 85 or 135... or if you're trying to save some cash sell either the 85/135 and then sell the 100L macro and replace it with a lower cost macro.
