Copper plate the frame;
pick out the lugs with silver lug lines;
Build up with chrome/shinny metal parts;
Hand built wheels with something like a CXP 33 rim (Brass coloured nipples?);
Cover bars in black sew-on elk-hide;
Black leather saddle; and
Veloflex gum wall clinchers/tubs tyres.

Althought the green brooks (with matching bar tape) would look sweet with copper.

That isn't that far off from my thoughts.
