This is a great idea, and it's been passed along to the gurus of the Cartel Market. I know I'd personally love to see this!
Here's my question for you guys: What character would you want to see as the Universal Crew Skill Trainer?
Continuing the theme of iconic characters from the current game, the next in line might seem to be Grand Moff Kilran... but I don't know how much sense he'd make as a crafting trainer.
(Also, if I had a Kilran holostatue, it would have to talk. Because I could listen to Simon Templeman all day.)
