It appears you have crunched all the numbers and have that part pretty well nailed. The part I question is where the hell will you find a dependable Co-driver that you could live with for 7,000 miles per week? I am pretty sure I am a lot different than you but such a co- driver would have to be one I could cuddle up with in the down times and trust with my life while I am getting some shut eye. There are a lot of husband/wife teams doing these types of runs. The No Deadheads is also interesting if you can make that really work.
