 I think that the best line for the priority pluralist to take is to deny 11, by holding that (i) entanglement represents a new fundamental relation between individual particles (as opposed to a new emergent property of whole systems), and (ii) mereological supervenience should be revised to concern the supervenience of the intrinsic properties of wholes on the intrinsic properties of their parts plus any fundamental (as opposed to merely spatiotemporal) relations among their parts. Entangled quantum systems so understood will now count as mereologically supervenient so  understood.[43]
