Although the timings for the early modules are a bit difficult to screw about with, those set in the US shouldn't be too hard to change to fit. As long as some lip service is given to events in other modules, there shouldn't be too much of an issue.
The capture/elimination of Carl Hughes for example in Kidnapped is going to have some serious impact on modules such as Urban Guerrilla. Probably not much on a number of other modules, not least being Satellite Down which really could be delayed by a year or so if needed (just have the satellite fall later). Red Star, Lone Star could be problematic given the Soviets precarious position and need for fuel and a way home sooner rather than later.
Note both Gateway and Going home can both feed into Kings Ransom, and almost anything can feed Last Sub (Going home, Armies of the night, Kidnapped, Gateway, even Satellite Down given the data is important enough to warrant an aircraft).
Red Star is the logical feed to Angels given that they are in the same general area, but Satellite may be a good option too. Angels could well be a good feed for Satellite.

And then you've got the various Challenge articles, not to mention scenarios presented in Nightmares, Encounters, etc all which have suggested locales.
