im pretty sure this is too much...each one of the lifts is supposed to have their own day. you are not going to be able to bench and squat heavy one day and then push press and deadlift heavy the next day all while doing assistance work.
do bench pushpress squat and dead on seperate days without doing two upper or lower days in a row and either do conditioning at the end of your workout or move it to a different day on saturdays or sundays
mon pushpress assistance
tue dead assistance
thur bench assistance
fri squat plus assistnace
