what would an electroplater say if you brought him some lithium cells and asked him to plate the aluminum terminals?

Tried that with pouch cells, they wouldn't touch them. Something about immersing high energy/power flammable cells into conductive liquid gave them concerns. Maybe if you can find a plating company more comfortable with handling batteries.
Many years ago, I used nicad AA cells in a product that required a long life and standard replaceable cells. The usual nickel plated end caps and battery holders are an endless source of problems when the cells get old and leak. So we had them gold plated. It was no problem to plate the ends of the nicads, since they weren't harmed by being run dead.
With lithiums, the only way I can think of is to completely insulate one terminal, and plate the other. Or perhaps, invert the cell over a cup of plating solution, and use the cell's own current to plate the desired metal (charge or discharge, depending on whether you're doing the + or - cell terminal).
