Yes true, and a lot cheaper to test whether the wheels are involved if you downgrade. Just regarding upgrades, if you're like me you need a logical rationale to upgrade anything so I'm not being flippant. Those of the other persuasion, who already have great wheels, it would be a good time to get a spare wheel-set or training wheels.
We don't actually know if the wheels have anything to do with it, in a given incident. I think that speed wobble arises from incidental combinations of practically any structural or moving components and/or the rider reactions.
