First of all, do you really need a long cage derailleur? I run my Nuovo Record with a 14-30 FW (42-52 chainrings), and it also shifted a 14-32 pretty well when I tried it. On another bike I have a NR with a Soma cage (a copy of the Rally cage), and it shifts a 14-34 FW very well. For a Colnago I would try the Rally cage on a NR or SR derailleur.
