You could use a screen shot of the map, zoomed out to cover the area of ops. Dull it up using photoshop and then call it up in the game as a titlersc or cutrsc. You would have to disable the in-game map.
If you think about, it would better simulate a paper map, which can't be zoomed like the in-game map.
Of course, you couldn't order units to go to map locations and there would be no updates to markers and the like. You could have several map screen shots to show different parts of the map or updated objectives, then just call them up at the appropriate times.
More work but probably more realistic.
