Reducing campaign layers = faster loading?

[GlobalExplorer]

Playing around with that new, lightweight parser that might be used for SHIV, I had an interesting idea:

What would happen if there was an external tool to reduce the campaign layers by removing all units that are outside the time period and geographical zone of the patrol? I'd guess you would end up with .mis files of only about 5-10 % the size of the complete ones, that I am sure of.

Now the question I ask myself are: Would this increase loading times significantly, or is the time used up for something else? And what would happen if the player loaded up a savegame .. would it be possible to manage the new campaign layers so that it would not cause problems on the users side??

This is basically a question to anybody with some experience with the campaign files. I just thought that theoretically it could be the starting point for a drastic reduction in loading times, the biggest problem I have with SHIII.
