I don't believe it's possible for dynamic link to work across versions like you're attempting.
Adobe didn't haphazardly make this decision just to inconvenience you.
Apple stopped supporting these older Quicktime formats, which means that eventually that would have repercussions for other production software. Dropped support for Quicktime 7 era formats and codecs
If you must continue using these formats, AfterCodecs may be a good solution for you.
Alternatively, you could keep an older version of AE + AME installed for projects requiring those formats.
