Yes, with 2 Kongou class and fast ships you can run the north route (A -> B -> D), and you only need to fight two times before boss node. If compass girl send you to deadend (J), just F5 (reload/force quit) the game. IMO you should use support expedition for boss node to kill those platform, 2 DD with 2 CVL/CV filled with blue planes should do the trick

E5 is easlier than E4, but you still need to perpare lots of resources for repair and supply. ~15k recommended.
