Since you're the author and I see the tool is in Python. I'm the original author of UnityPack (https://github.com/hearthsim/unitypack - nowadays, the fork UnityPy is more powerful and maintained: https://github.com/K0lb3/UnityPy).

It's in Python and is able to deserialize Unity archives, treating them as a serialization format rather than a simple archive format. Feel free to email me if you want to integrate something like this or you have questions :)
