No benefit, and just addition places for it to leak. Things like this are great for cars the oil filter is a PITA, on the g35 is easy to get to.

 

I had a complete remote oil bypass system installed in my G when I first bought it. I ended-up removing it because the full flow relocation caused some strange noises which I believe to be either a harmonic vibration from the oil lines or something to do with the oil pump. If I were you, I'd keep the filter where it is, and just add single remote bypass filtration unit and a pre-oiler. Do this without re-routing the full engine oil flow.
