Totally possible. In general I believe that while more powerful in their best outputs, Sonnet/Opus 4 are in other ways (alignment / consistency) a regression on Sonnet 3.5v2 (often called Sonnet 3.6), as Sonnet 3.7 was. Also models are complex objects, and sometimes in a given domain a given model that on paper is weaker will work better. And, on top of that: interactive use vs agent requires different reinforcement learning training that sometimes may not be towards an aligned target... So also using the model in one way or the other may change how good it is.
