The Twins do have Lopez, Ryan, Ober, Paddack, and Woods Richardson (plus Festa, Varland and others) under contract for 2025. This isn't to say that that rotation can't/should be improved, but given that July is always a sellers market, I'd rather only pay a premium for a half season than for 1.5 or 2.5 seasons.
Additionally, I think all three of these teams are such that they aren't ready to punt 2025, so I think they'd be reluctant to trade guys they have under control for next year.
That said, I do agree with your prediction that the Twins do more tinkering than making a big splash.
