Hi Scott,
     Copper plating tungsten is very simple actually.  I've done a lot of plating myself.  All ya have to do is electropolish the tungsten( I taped off the ends of the rods, cuz I figured there was no point in plating them) and use a basic copper electrolyte solution.  I think I used about 50g/L copper sulfate and about the same of sulfuric acid.  I am sure one could optimize that...but for a one shot deal...why bother?   I used a D cell battery and a variable resistor as the power source....very crude, but effective

  I figured the gap would blow the plating off the tip, But I use a 
propeller 
style gap, which means I have 7 inches of 1/8 tungsten rod.  Still 
probably 
negligible, I figure If I use an acetylene torch to melt some copper, 
it 
will stick nicely to the heated rod, just like steel does (although 
this is 
bad for TIG welding).  Or I could electroplate the rod, if that would 
work 
for tungsten (I have extensive experimental copper, zinc and silver 
electroplating experience, I can get most anything to stick to most 
anything, assuming I have pure samples of both metals).  Just musing.
