Guide Nickel Electroplating and it's effect on cooling capacity of heatsink

Hey guys, I've got a cpu cooler( noctua NH D15) and the fins have discolored due to age so I was thinking I should electroplate it with nickel. I've done nickel Electroplating previously but I'm worried if it will have any kind of affect on cooling capabilities of the heatsink as it has copper vapour tubes.
 
I say don't do it. The copper pipes are sealed, if compromised the liquid/vapours will escape, dropping the performance. Look into methods to restore the aluminum which are not harsh.
