It's possible, but it would have to be done as a single mission that just keeps going. It would be impractical to make an MP scenario like that because of stability issues and the lack of a save feature. In SP it's definitely doable, and Bill Nichols did something along those lines with
Sicilian Wedding. I'm not aware of anything else like that, though.
Maybe I'll put it on the list. =) I'd like to make some new missions once we get 3.10 out (just waiting on an installer package) so maybe I can try my hand at that, provided I can think up a design concept anyways.
