You can do a one way DME reservation,,,, but the Poly tags are going to be dated for the day after they arrive and I don't know if the handlers will know what to do with them. Chances are the bar code won't read properly and they will have to read the tags and decide what to do, they may send it along to the Poly but then where would they go until you arrive the next day?
The other issue I see is that if your flight is late or the luggage is delayed they will be sent to the carousel if it is after 10. They will sit there for a while until the airline baggage handlers pull it aside. Now its in the luggage office and again who knows if/when the DME luggage handlers, who are behind the scenes and pull tagged bags prior to the carousel will check the baggage offices.
Neither is something i personally would try with our checked bags (and I do use the DME delivery often)! Honestly if my flight is scheduled to land after 9 I won't take the chance on bag delivery and pick my bags up myself.
FWIW bell services will move your bags from Pop to Poly for you while you head to the parks, this is what I would do!
