I thought it would be the easy option to get several 'games' in a single mission. The result is here:

The main structural issue is that you can't rely on synched WPs with groups that can be player-led. Early attempts used switch triggers but I went off these and, er, switched to using WP conditions to control the flow. Feel free to have a look at the .sqm but bear in mind that it has evolved (i.e. it's an untidy mess) and I would now do it differently now I know how I did it. Not sure I can face it, though, I'd have to learn dialogs as that'd be the expectation nowadays.
Game-wise, the problem is that the bigger the operation gets, the more irrelevant the player becomes and/or success becomes a lottery. To be a good game the player needs to either make a difference or, at least, feel like he does. I don't know how close I've got to that ideal in 'A Touch of Frost'.
I can't actually see myself making [m]any 'one-off' missions because of the work involved in overheads like cutscenes, realistically dressing the set or whatever. That's where the savings in effort are made.
I have also got a 'works in progress' that uses the 'series of missions' approach as well. This'll be a pair of missions: one played as East, the other West. Time will tell on that one but don't hold your breath . . .
