me personally i wouldnt like to train back twice week but may work for you i done this for arms when thought wasnt growing and found training twice week hindered them but as said could work well for you
if i did would keep it simple
day 1
latt pull down
close grip cable row
barbell row
deadlift
day2
pull up (assisted if needed)
dumbell row
hyperextension
invereted body row
this doesnt include traps
