Doubt it, unless Azmuth found a way to retaliate the "Electricity" weakness they have by making their "corpses" absorb energy, which would make Upgrade merging with the watch a good explanation as to why the armors come from Shock Rock.

I think when Upgrade sacrificed himself, he simply merged with the watch. And to avoid glitches or a paradoxal feedback from the Omnitrix (or just Ben upgrading it to the point it overloads and explodes), it deleted the DNA sample so there wouldn't be any error coming from the system. Just a theory though
