No, I still have half wire and half Dacron line. This works well for me and I don't plan on changing it since i don't plan to run all lines to the cockpit. I'm fine with going to the mast.
I'm not too sure there is enough room in our masthead for all rope sheaves. Its pretty tight inside that masthead. You'll have to measure it carefully.
