Technically he already is or at least the Zahn Consortium is. Not every legends character needs a reintroduction into Canon as they just won't have the same levels of prominence in modern stories as the major ones have already been written. For example if you bring back Mara Jade you won't be able to do very much of her later life if at all.

Canon has some interesting crime lord type figures like Dryden Vos so it could work but only if he is included in a decent medium of storytelling.

I'm increasingly of the opinion that Canon should be entirely original.

Let him stay in legends

I want the reboot to stop appropriating characters and worldbuilding from the original saga. They don't want the stories, so they shouldn't get the characters. If they want to do stories with Thrawn or Tyber Zann or whoever, they can set it in the original saga.

Legends is the real canon anyway

^ I'm afraid $4 billion says it's not.

Unless you've got at least triple that lying around you're just going to have to like it or lump it.
