Welp, I'm a natural multi-shipper so broadly any/any + convincing author (or dynamic I like), but I'd prioritise the following: Baze/Chirrut, Chirrut/Bodhi, and I surprised myself by shipping Jyn/Cassian. For the villains, I'd be interested in seeing most variations on Tarkin/Krennic or Vader/Krennic and some very specific flavours of Krennic/Galen. I would be beyond delighted to see Leia/Jyn, but I suspect the necessary AU-ness of it will mean it remains rare, but hey, hope springs and all that.
