I'd personally go for a bob jackson/mercian/rourke etc audax setup in 853 os if you can stretch to it (fillet brazed or lugged whichever), and maybe put on a columbus carbon fork and 'classic looking' silver parts... then with decent hubs and open pros and a campagnolo groupset you'd have a really nice bike.
Pretty pricey though..
