I may also simply be unaware of the possibly similar works on this problem too.

Recorded compatibalist conceptions of free will are several centuries older than academia, so I don't think it was ever really a publishable insight. (You got it on your own, I got it on my own, and so have a lot of people throughout history - it's just that not everyone agrees.)

I don't know about the second question...assuming the premise is true, I suppose either they did not try or it wasn't accepted, I'm not sufficiently knowledgeable about academic philosophy to speculate!
