Theorically yes, pratically no. From my experience when your support ships are in red fatigue the flaship CL can trollolol you and survive to torpedo phrase and red a red fatigue CVL easily. With the mutiple flagships in world 5 A nodes the chance is muliplied, not to mention the flagship CA will just ignore your subs and proceed to red your red fatigue CVLs and even the BB easily.

Additionally it's harder to hit and damage flagship lvl shipsin red fatigue. So unless you are letting your ship rest from fatigue this method will not work. (Remember you can run 3-2-A even when the support ships are in red fatigue)
