Sorry! I kinda forgot about your original question.
Cleans could be cool on day 4 as more back work.
Or you could do some easy upper back at the beginning of day 5, to pull your shoulders back, and "support" yourself better on the incline benches.
But you may find that after the snatch grip dead on day 1, squats on day 3 and rows on day 4, that there is no way you could do power cleans.
You just have to kinda jump in there, try it out, and see how it works. Is your injury "fixed"? Can you get into position do all these lifts? It looks like you're trying to hit every muscle group, can you really "feel" all these moves? Basically, if you can't get low enough to snatch grip deadlift, you can snatch grip dead out of the rack until you develop the ROM. If rear delt flies don't pump up your rear delts, jump on the pec-dec backwards and see if that's better. Don't chain yourself to these lifts, stick to the "intent" of the lift.
The frequency is high, and like Dagil mentioned, lots of iso moves. But that is probably a good way to come back into the gym after an injury. Make sure everything works. You can always rotate more heavy work like cleans, close grip benches, front squats, seated dumbbell presses into your "B" group as you get back into the swing.
You pulled 460! you're on the right track, and you obviously have some idea whats going on.
