I mean, it's possible she defeats amon, teaches the zerg about human emotion, then manages to use the artifact (or similar device) to return to human form and live happily ever after with Jim, right?
or is that too cliche and sappy even for blizzard?
The real reason why this is unlikely is cause there protoss need to become part of the story
So far zeratul just shows up and says blah blah have to do stuff, bye - and apart from some random protoss cults and the end of world mission in WoL there isn't really any protoss participation.
Given zeratul's "rogue" status with protoss I think ultimate conclusion will be him bringing the 3 races together to fight amon
Also to Dox's point regarding why she cares - I believe this time as queen of blades she retains her kerrigan identity and her human emotions etc whereas before she became amon's tool or mindless puppet kind of thing
