You could contact LN Engineering
https://lnengineering.com/ and ask. I think the plating was designed for applying to aluminum. Even if it could be done I think the main benefit of heat transfer would be lost.
If you want Nikasil, I would look to buy actual 86mm Nikasil cylinders. LN Engineering offers them. A bit more low budget but I don't know the quality is QSC.

Henry Schmidt used to sell them, but I think quality can vary.
