You've listed a set of varying compositions, not tempers.

I almost positive that 6061 accepts coatings well. I'm not sure about the other compositions.

And no matter what the composition, a zincating dip will be required (and possibly a plating of flash copper, depending on surface quality).

I use 6061-T6 in a lot of general applications. I have never had a problem with it accepting a surface coating, but I can't remember off the top of my head if I have ever had to have something in aluminum chromed.

If you went with that alloy/temper combo, I don't think you would have any issues at all.
