Yes. You've come across a problem that I was bitten by earlier, when I discovered that the nickel parameters were zero.

A former colleague of mine, Dan Sindhikara, used values of 1.10 and 0.013 (cf. Zn2+) for Nickel. See here:

Biochemistry 2009, 48, 12024-12033

For copper, I don't really know. Martin, do you have any suggestions here?

Cheers,
Ben
