If you can't pull from the floor, why not just do the hang full snatch/hang full clean? Start at standing straight, bend your legs, do a Romanian deadlift but stop at lower knee, and then do your thing (I hope you know what to do then...).
In my opinion, if you do not have the mobility for a full snatch, you should do the Texas Method: http://www.T-Nation.com/free_online_article/most_recent/the_texas_method
No snatching. Just squats, bench presses, and power cleans.
But since you posted your own routine design, let me go ahead and check it out...
The way I see it, with your MWF, weighted chin-ups and weighted wide-grip pull-ups aren't necessary... They may even sabotage progress.
The way I see it, with your Tues and Thurs, the Push Press and ab work are all you need.
