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....
Let me tell you from personal experience what happens ion the case of wires shorting to ground ...
In the case of a heavy gauge wire like the battery positive, it will literally blow off at the weakest point - in my case that was at the negative frame mount. So other than that, no damage to the car.
In the case of a thinner gauge wire, the wire will heat up and melt the insulation off its entire length and do the same with anything it comes in contact with. Anything flammable will catch fire and in the worst case, burn your car to the ground.
Give me a heavy gauge short any day !!!
