On the topic of canonizing stuff, I had a feeling they were gonna use the Outrider from Shadows of The Empire at some point. The ship itself is still in the most recent releases of ANH so it’s no surprise to me, hell Disney even made it canon ages ago :http://au.ign.com/articles/2015/04/30/shadows-of-the-empires-outrider-confirmed-as-star-wars-canon
There’s even a YT-2400 showing up in Rebels soon.
