It seems that the 2018-2019 rim brake generation of the supersix are few and far between (older versions around, but I seem to remember that 2013-2016 versions had the tendency for serious tyre clearance problems if you were unlucky? Plus the version that has the 25.4 seatpost is the 2017 version)
So I was wondering (to solve the 31.6 seatpost side of things) - what about if I just shimmed down to 25.4 and put in a cannondale save seatpost? How shit would that look? Practically it seems that it should clamp ok, with enough carbon paste

I’ve found a version where someone has shimmed down to 27.2 and that looks fine - plus had the added bonus of weight saving (https://weightweenies.starbike.com/forum/viewtopic.php?f=10&t=127910)
