What ever happened to ( or what will become of ) Sidon Ithano? I think he would make a great candidate ( along with Doctor Aphra ) for a canon scum pilot. If the Quadjumper can make it, we can get Sidon. We see his ship ( rear end at least ) in Force Awakens and we know it's a modified version of an established canonical CSS-1 Corellian Star Shuttle. Film appearance? Check. Canon story appearance ( The Crimson Corsair and the Lost Treasure of Count Dooku )? Check. Let's doodiss!

P.S.
Not that canon necessarily matters. I enjoy the legends scum pilots, but I think we could use some more canon ones along with them. Just my opinion.
