New Game Style?

I thought of a new game play style. What if a certain player was assigned to take over a certain continent (by the beginning of a turn, not the end) to win the game.
Using Classic as an example, say that I was assigned to take over Africa. I might take it over in a few turns, but then another player might take North Africa from me before the next turn. I have to hold it until the beginning of my turn to win the game.
It sounds stupidish but it may be worth doing. Thoughts?
