I dunno if Trips would ever do it, but in a perfect world, Dustin gets secretly signed.
Cody & Roman do this tag match with the Bloodline that somehow spliters Roman off to feud with Bloodline Wolfpack, freeing up Cody.
Have a SmackDown where Cody is about to get jumped (or gets jumped) by Bloodline Wolfpack, only to be saved outta nowhere by Dustin. Get the huge pop from the crowd, they hug in the ring, feel-good moement, then BOOM, Dustin attacks him.
Dustin goes on to do the disgruntled brother thing, Cody got the success he shoulda had, everyone thinks better of Cody, Cody even stole half of Dustin's moves (e.g. - the drop to his back & punch), etc. Now that Cody is the over-the-top, blonde-haired, blue-eyed babyface, Dustin is here to show the world the "real" Cody...that he's fake - just like his blonde hair.
Then build up to an intense blowoff PPV match. Give 'em 30 minutes and let them absolutely tear the house down.
I would be ALL for that.
And I'm certainly more interested in that than Cody vs quite literally *anyone* in the fucking Bloodline.
