Shang doesn’t have a lot in common with Bae. Other than dark hair and eyes, I guess, but Bae is not a soldier as Shang was. If they’re going for a mash up, I guess they could pull something with MAP having to fight the Ogres, and Mulan is the general, and Bae the recruit, but I’m pretty doubtful. I won’t say it couldn’t happen, but it doesn’t sound as nifty to me as getting a better understanding of the Milah situation/closure, or Hookriel (since that was around before the show, and the season started, since there’s the shared love of the sea for pirates & mermaids) or the snarkfest that could be seeing Regina on the prowl again like with Graham.
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
