Im pretty sure that Micro wheels aren't actually made by Micro. Someone has found a roller skiing website with identical wheels (that's also why they are not as durable as they used to be). Right, now they have 'micro xtreme' printed on them but that is only a matter of contacting the real manufacturer or even can be done after they order the wheels. The Micro-xtreme.com shop is owned by Eric Rabl who personally does all the modding job with the reinforcements (really easy to make out of standard aluminum profiles), extra folding mech plates etc. So I don't think that this shop would sell metal core wheels (unless they were going to be priced unreasonably high, as the real manufacturer is unknown, Rabl would be necessary as a middle man) or reinforced micro models.
