I want Hux to actually do something. Perhaps while Snoke is training Kylo Ren, he cannot be reached, forcing Hux to take matters into his own hands and consolidate power under him, while Phasma (assuming she survived TFA) becomes his enforcer/bodyguard, a la the Tarkin/Darth Vader relation in ANH.

I feel like the governor roles in the movies were underutilized after ANH, ending up more as obstacles to Vader than actual villains with their own agenda. I’d like to see them becoming a meaningful threat again.
