TK-27 Direct Bolt on Replacement for TK-26?

My GPz 550 project is coming along quite well right now, I'm about to order new O-rings for the carbs, but I remember seeing somewhere that the TK-27s on the later GPzs are a bit more trouble free in the long run and have the idle adjustment on the side instead of the center, and this got me thinking that maybe it would be a worthwhile change if I'm about to spend the money and time on rebuilding the carbs anyway. What would I have to change on the carbs to make this work, based on some research I'd have to replace the pilot and main jets but is there anything else like rerouting vacuum lines?
