Villains journey event?

I think I’ve heard this mentioned before, and yes I know it’ll be a ways away since we just had jtr released, but any chance of having a “villain’s journey” style of event? An obvious candidate would be Darth Vader, which could bring a nice twist in requiring both dark side and light side characters (Jedi Knight Anakin, Darth Sidious, Padme, Rex, etc.). Anyone else have thoughts on this?
