Your examples of public domain movies take a rather flexible view of the source material.

Frozen is a long way from The Snow Queen. A queen had powers over ice there where trolls and someone was saved by a kiss, but in the Snow Queen it was a guy saved by the kiss and the trolls where evil etc. I wouldn’t be surprised if someone at Disney read it, but I wouldn’t count on it.

Peter Pan, Little Mermaid, etc adaptations at least share some basic elements of the story though their at most fanfics and really that’s all I am advocating.

Nobody is going to pay for the rights to the Hitman video game franchise and create The Professional. Because if you mutate the story that much you’re legally in the clear.
