Just install the new plus as they come out of the box.

Never use copper paste for spark plugs or any part made from aluminium like cylinder heads. Copper paste is conducting so keep it away from high voltage (or even low voltage) parts. Copper paste will boost corrosion of aluminium (cylinder heads).

This MAY work and you MAY not have any problem but its for sure not recommended. In general you don't have to use any antiseize on spark plugs but if you really think you have to use it ... try other products like ceramic-based anti-seize.
