It is too dangerous to do this (using cyanide).
I think, it would be better to check if the higher thickness of gold plating (on
fingers?) can have an insertion problem. Higher gold thickness does not affect
reliability (solderability), it is good for customer but bad for the supplier
due to price of gold.
If you are trying to remove 1 microns, you can not be sure that the etching is
uniform throughout.

hope it helps
