I think you completely miss the point of doing that.
The cable needs to be run to the front of the car in either wiring method.
The benefit of having the starter relay closest to the battery is that in the event of a crash or fire, you no longer have a heavy gauge live wire to short to ground.
Or the relay can be placed up front, and now there is no chance of shorting the start cable changing a trans, etc....
