I was actually arguing more-so in the favor of characters who are only Spirits, or were an Assist Trophy previously but aren't in this game (although I'm not sure which characters those could be tbh).I don't quite think that's the case either. As far as Assist Trophies are concerned, I feel like their only chance now is if DLC support continues going on strong and we run out of candidates for whatever reason. Take JDog's post for example:
Putting aside the T-Pose-ish nature of these hilariously-unfinished grab animations, it's possible certain Assist trophies may be promoted in the future. The characters aren't exactly new to Smash, but keep in mind that Reggie is specifically referring to the advertising nature of the current Fighter's Pass. If we are to assume that there are future Fighter's Passes, the intentions behind them may vary.
I know that current ATs are very unlikely to be promoted (although I believe they could do it if they wanted to; just make a certain AT unavailable if the fighter is present, just like how it does to specific ATs on certain stages).
