Turn-Based Victory

I HAD AN IDEA:

How about a turn-based Victory? The players could choose their Victory style at the beginning of the game. Then the players pick a Turn-Based victory, such as, "at turn 350," the scores are compared. 

So, if one player picks Dust Victory and the other player picks a Conquest Victory - at the end of turn 350 - the scores are compared and a winner is picked!

I think this idea would bring more strategy and aggressive game-play.

Let's say, I pick Dust Victory, but my opponent picks Conquest Victory - It would be challenging to raise my score level and preventing his score level by the end of, let's say, turn 150.

Any feedback or thoughts are welcomed. Was this a helpful idea or suggestion?
