The Consortium was lame.
But their ships were awesome. So I would not mind seeing them in game.
As to criminal organizations realistically not having the needs / resources / crew to run star destroyer sized capital ships, its a fantasy setting with magic space wizards. I don't think some criminals with a couple big ships here and there is that big of a stretch.
Also, the Shadow Collective is a thing. Don't know if they have been acknowledged as existing post CW, but they were intact the last time we saw them.
