I see where you are going with this, but I am not sure that you are going to give yourself enough recovery time for your legs. Overtrained legs dont improve. If you are dead set on a 2 leg workout week, you need to reign in the volume

As an alternative, I would suggest this.

Monday: Back and legs(1)
Full deads
Dumbell Rows
Stiff leg/Romanian Deads

Tues: Chest and Tri's
Incline Barbell press
Weighted Dips
Close Grip Bench
EZ Skullcrushers

Thurs: Legs (2)
Front or back squat
Overhead squat or box steps.
Calve raise.

Friday: Shoulders and Bi's
Standing barbell press
Lateral raise
Dumbell Shrugs
Standing dumbell or barbell curls
