Charging system and other wiring change help needed

I am hoping to get some response back on my thoughts below. Please be honest on your thoughts. You wont hurt my feelings. I really only want to do this one time.

I am going to be trying to hide as many wires as I possibly can. Here is my thought for the passenger side for my alternator wire that goes from the alt to the Battery in the trunk. I am using 1/2" aluminum line for a carrier out under the passenger fenders. The tube goes into the passenger compartment just behind the heater box. It will then go down behind the kick panel and and follow back thru the passenger side channel and into the rear compartment then thru the trunk to the battery. It is an 8 gauge wire. I will probably put some sheathing around the wire while it is in the pipe but once its in the car not sure if that needs covered. If this works I will probably do the same on the drivers side for the feed wires for the relays. I also bought 25' of 5/8" aluminum line that I could also run my starter wire out under the drivers fender. The one thing I am finding out is that I will need to put the wiring into the pipe before I bend it because it is so stiff that I won't be able to snake it thru once its bent. Here are some pics:
