I've completed my conversion, cinelli 8001 from 1987, changed only handlebar and stem. Brifters are campagnolo xenon 9v, work perfectly with original 6 speed xt group and front derailleur.

Since i've less than 10 post i cannot put images, but i leave the link on pedal room:

Really happy with the result, with continental speed king and latex tubes is fast. Brakes are... Interesting front xt cantilever and rear ubrake.
