Question Plating gold/copper alloy (Shakudo) on copper

I would like to plate shakudo (4%-6% gold in copper) onto a copper subtrate for subsequent patination. Shakudo takes on a dark black/purple hue when properly patinated.

Can a standard copper plating system & solution be used with a shakudo anode, or will the copper selectively plate out leaving the gold ... or vice versa?

If necessary, can a copper plating / gold plating solution be combined?

What brightener should I use to keep the plating uniform, smooth and bright with minimal oxygen inclusion?
