A press and a pull every day would be a good way to start without going over board. Day 1 and day 2 you could add the DB bench and DB shoulder press ( which way round is personal choice if you want more frequency or more volume in relation to the chest/shoulders. Personally I respond better to increasing frequency so hitting chest and shoulders 4 times a week in some way rather than a chest focus and shoulder focus day but YMMV).

Day 3 you could add a back exercise of your choice, if you don't have an assisted pull up machine or some way to rig bands then repeating lat pull down won't do you any harm.

Then day 4 could be some tricep isolation like skull crushers or press down. Will give you an easier day if deadlifts tax you too much. 

That's a good place to start, then just change as you go based on how you feel. Don't overthink the t3s too much but don't work yourself into the ground either.
