rendering Baldur's Gate 3: Split Monitor Local Co-op

[Neuffexx]

An idea I recently had was, for people who are playing local co-op but dont want split screen (due to wanting a larger view or anything else), but do have two monitors, rendering the second players screen into an entirely new window.
So rather than splitting the view, you'd have a new window be created.

Would that even be possible?
That would potentially make more than 2-player local co-op more feasible rathar than divind a screen into 4, even if its just two windows split amongst 4 players.
