Duke already has this in the form of the GLS program:
https://liberalstudies.duke.edu/
"Duke GLS is a flexible, self-designed master’s program grounded in the interdisciplinary liberal arts. With part-time and full-time options, we offer learners of all ages and backgrounds strong academic and professional development support and access to the scholars and resources of one of the finest universities in the world."
Of course, GLS
can be very academic, just depends on what the person wants given it is "flexible" and "self-designed."
I'm sure many other institutions have something similar. And a 1-year business program (MMS: Foundations of Business).
