Please critique my strength and conditioning program

I have been kicking around a basic template of a Barbells+Kettlebells program that is 5 days a week. My goals are to press 180, deadlift 400, and get the 200 snatches in 10 mins with a 1.5pood kb. It looks like this:

Monday(light)
Press 5 sets of 5
Deadlift 5 sets of 3

Tuesday
Pull up ladders
Kb circuit or x-minutes of snatches

Wednesday(medium)
Press 5 sets of 5
Deadlift 5 sets of 3

Thursday
Pull up ladders
Kb circuit or x-minutes of swings

Friday
Rest

Saturday(Heavy)
Press 5×5
Deadlift 5 sets of 3
Max pull ups
Max snatches

Sunday
Rest

I based this off of Pavel’s stuff in etk and Bill Starr’s Heavy, Light, Medium concept. The light and medium days will be based off of the heavy days last set. My current PR lifts are Press-135, Deadlift-335. I haven’t tested the snatches yet and my pullups are terrible. Does this sound like too much for the low back to recover from? Any advice would be appreciated.
