Electroplating Over Solder Joints

We have a need to electroplate a nickel passivation layer over soldered joints.

Do you know which type of solder would have better electroplating properties? 60/40? 63/37? Pure tin?

I would go with pure tin as it would be the most conductive and also cut out the risk of issues with different plating thickness on tin versus lead, the solder joint is a mix of metals so areas will be tin or lead rich. How ever I have to ask why would you nickel plate over a solder joint?
