Possibility of a drop-in replacement for existing games

[ThreeDeeJay]

I was wondering if there's a possibility that Steam Audio could ever be compiled into a DLL replacement for pre-compiled/released/commercial games instead of requiring the source/project files.
Like, in many older Unreal Engine 3/4 games, we could add a DLL and HRTF files to get 3D audio using this: https://github.com/kosumosu/x3daudio1_7_hrtf. But since around UE 4.2x (at/around the time support for external spatializers was added), that plug-in no longer works, so it would be nice to have an alternative for HRTF/3D audio since it's rarely offered, especially in Unity, FMOD and Wwise, which I'm assuming would need to be modified as well to let Steam Audio handle audio mixing, unless it can be a self-contained static replacement 🤔
