You can’t really depend on Crochet for anything this year. He’s going to be busy getting himself right.
If you trade Liam, you better be ok with seeing more Kelly, Ruiz, Diekman, and Lambert in higher leverage roles. Because everyone is going to be bumped up. I don’t have faith that Graveman is going to be fine - he looked very human at times last year, and we have no idea if Lopez is even capable of being a 9th inning guy. Think of how well the Matt Thornton experience went when Jenks was finally cut.
Losing Hendriks, while possibly improving a different area of the team will make the bullpen a mess IMO. You’re essentially banking on the lineup being able to put up runs consistently to keep them out of tight games.
