I actually like that idea, but there are still some logical hoops you might need to jump through. Not only might you need to establish Holdo knowing about the device, but also where on the Supremecy the device was located, otherwise it seems like a very big coincidence.

I kind of think it would be simpler to infer that the entire ship has some kind of “hyper-field mumbo jumbo” charge generated as a result by the device. But maybe the hologram would imply they have some kind of schematics of the Supremecy?
