#4 Lince Dorado

This is a bit of a stretch, but there's already a precedent of Raw Superstars managing talent from the cruiserweight division with Titus O'Neil branching out and acting as a mentor to Akira Tozawa, so the same could apply to Goldust.
If that is in the works, mostly everybody has some kind of gimmick or shtick outside of Lince Dorado, who hasn't had much notoriety since joining the roster after the Cruiserweight Classic tournament.
His talent is almost going entirely to waste as he's infrequently used, so for him to be paired up with Goldust, it certainly wouldn't be a demotion.
Obviously, the major connection here is that his name translates to The Golden Lynx and that may be inspiration enough for Goldust to want to set his sights on him.
If he's scouting talent that he can mould, we might start to see Goldust's influence on Lince Dorado start with a redesign of his ring attire to reflect more of the patterns we had seen in something like Stardust's gear and such.
It might not be the best idea in the world as far as logistics go, but it's something to ponder about.
