What model is everyone using for magical transformations/morphs?

Back when, I started using Luma AI because Ray1 and Ray1.5 were really good at transformations - a character seamlessly evolving from one shape into another - a bear sprouting wings and having feathers extend out from under the fur and its stance changing to become an eagle, as talons extended from its paws. Or something more fantastical. A coherent structural change over time in the character. A true morph while the character was in motion.

As those models matured, they have (like most models), gotten far more coherent and adherent. For most gens, this is good thing; you want your model to follow your prompt verbatim. But in doing so we have lost the hallucinatory aspect that older AIs were so good at.

Same goes for all the other models that Luma hosts (Seedance, Kling, flux, veo, Gemini etc) - they are just so coherent that they won't allow these kinds of flights of fancy. You used to be able to put a start frame of a bear and an end frame of an eagle and the magic would happen in between (steered by a prompt).

So I'm looking to augment my daily driver of Luma with another model that can do this. Paid or free, don't care. Ideally with start frame/end frame support.

Any suggestions? Any "magic words" to suggest in the prompt?

Don't get me wrong. They will have to pry Luma from my cold dead hands - I just have the occasional need for something fantastically transformational.

TIA
