ABSOLUTLY NO
You should never mix up a set of pistons, or replace only one piston.
They are made in batches so they all match in weight. If you swap out
only one piston you will end up with an out of balance situation and
you will have a vibration coming from the engine.
Yes there is a possibility that you may get a single piston that is
the same weight but is it worth the risk Is the time to remove the
engine and re do all the work worth it.
