Compared to copper, gold is a poor conductor - you would be building an
inferior cable
If you use a single strand then either copper or silver would be much better
Going to multiple strands of copper you have to think about stopping the
conductors from tarnishing inside the insulator.
This is not such a concern with silver, since the black tarnish also conducts
electricity almost as good as untarnished silver believe it or not.

So why do they use gold to plate RCA plugs etc...? Because it does not
tarnish and it looks like a quality product. Not because of its electrical
properties. Rhodium is even worse, but it's a lot tougher than gold and
doesn't wear off as easily.
Good luck :-)
