Honestly, I find this to be pointless. What would be the point of a cyborg xenomorph? Who would gain from such a creation?
A mechanically enhanced xenomorph would, if anything, be weaker that in its natural form.
Its mechanical components would be unable to withstand the extreme temperatures or elemental changes which its organic body normally could.
Additionally, possessing machinery translates into increased weight, making the xenomorph slower and less agile.
Robotic components would also present a chance that the xenomorph would be incapable of reproduction or natural survival.
Finally, organic parts grow stronger as they are used more. Machinery breaks down. It would only be a matter of time before the creature would be unable to function and would die.
And thus I clothe my naked villainy
With old odd ends stolen forth from holy writ
And seem a saint when most I play the devil.
