Hey there
I feel you on the flow of the movements our bodies tend to quickly like and adapt to the your rythem and sequence of ex's... It's just what the body does(adapts to stress... Putting your body under Stress is what makes it grow)... So just think about your compound movements(yours being basic but most effective - best kind imho) which are for adding strength... Start with your bigger BPs... Why? They will expend the most energy whether it's pushing or pulling right
Got cha - so by hitting all these ex's in one day is fine but by switching the order around
okay (keeping it in a push/pull manner) is important in helping you not shortchange your BPs(by giving the pushing a break when pulling) I think this will help your intensity as well
great as flow in more fluid way(maybe)

-- legs... I'd say squats, static smith machine lunges(glutes), if your looking to lean out and add accessory lifts... Cable rev leg raises, hypers(for lumbar development - good complimentor), leg extensions/leg curls, RDLs/stiff legged deads, deadlifts(posterior chain hams/glutes/, etc
WHEW! got cha
And consider this our arms are our smallest BPs - and they are being worked each time you push or pull(synergistically) - they will be tired but it's like a method we use in HIT(pre-exhaust) by pre-exhausting them you won't need as much weight but you'll get the same results
sounds good to me with less possiblitliy of injury as well! Just something to think about
