Installing Windows Mobile on a Palm OS device?

So I have a Verizon Wireless Palm Centro. It comes with Palm OS installed on it. I was wondering if there was some way to instal Windows Mobile on it (legally or not) while still keeping my service provider and not affecting my plan or any of that. In fact I would not like to go through my service provider at all for this instillation. Is this possible? If so anyone know where to get started? Thank you.
