If it ain't Berrios, I like your reasoning and it could be a really fun kind of wild card cup of tea moment for Romero. Though, If he's not called up for the rest of the year, you've just thrown away his first option season. We started Polanco clock a couple years ago just to have him sit on the bench, which is why we got to watch him hit .190 through July.
It would be fun and I would cheer real hard for Romero though.
