Yeah, I was trying to think of a better word than chubby, but all I could come up with was not-lean. :P

But yeah, I still think the people who CAN and DO pair him, are people who like the enemy-to-lovers thing, or villain pairings... where I just do not!

But, if you picture him going through the same personality changes as Cas (or similar), I could totally see pairing him after all that, when he's essentially a different character than when he started (like Cas is now.)
