I don't think so. I think taking back another contract that is inflated (but to be very clear, the player is still productive) should be in bounds, but there's no reason to act desperately. Bellinger's a good player and he's not a terrible fit on the roster. I'd prefer if he were RHH and I'd prefer if we could count on him for more dongs, but holistically he's not really any better or worse than FA alternatives like Teoscar Hernandez or Anthony Santander.
For instance, someone brought up Schwarber for Bellinger. That feels like the type of thing that feels more appropriate. Like I'd say no to that specific move, but it feels imminently reasonable.
