Can I use MotionMatching plugin of UE5.3 on UE5.1?

I was wondering if there’s a way to downgrade plugin (since in ue5.1 motionmatching is very different than ue5.3) and be able to use it’s newest features on an older version of the engine which it was not designed for

Maybe, if you can be bothered to recompile the source code, but probably not…
