I have a hard time imagining a situation where that would come up.
Looking at the CDU's actions whenever they're in power (whether that's back under Merkel or to this day in multiple state governments) they're almost completely aligned with the far left. Actions speak louder than Merz' empty words.
Plus, they would have to appease the SPD who are barely any less extreme than the other far left parties.
