The xenomorphs take on the genetics of the host/impregnated creature; not its technical aspects. eg if an egg was laid in a human with an artificial leg, the xenomorph wouldn't incorporate the titanium, polymers and whatnot the artificial leg is composed of.
But entertaining your idea that the xenomorphs could take on Borg technology after gestating inside a Borg drone, said xeno-drone would likely be under control of the Borg hive-mind (ie qeen). So you see, resistance is still futile.
