 I don't think so.

I completely agree. Although I heard very convincing AI based
extractions of drum parts from instrumental tracks and imagine this
could work very well for your application case, I would expect you
need a fair bit of training data and expertise to make it work.

I'd be quite interested to hear about your experiences and results
(just post offline).
