muahhaha already am doing that...
i see what you mean but i like to work out in 5 day cycles...the way i look at it is
2 days for arm/chest/back then one day legs (rest for upper body) then 2 days arm/chest/back then 2 days rest
as for your last part i am already doing that two ....i switch up daily between bench press, machine work, and barbells for a full effect on all my muscles
