How would that even work? Even with a Congress that works more efficiently than this one, you can't put a bill in at the last minute and expect it to to go through. Also, Disney has had a very public fight with DeSantis this past year, and Republicans would block the effort merely out of spite.
They don't need to have that fight. They got what they want with Trademark law now. Steamboat Willy will be public domain as expected this Jan 1.
