You might be better off doing 5-4 for Shoukaku. Not only can you level your ships (CV, CVL, CA, CAV that you'll definitely need) but can aim to get Uzuki here for chain quest. I find it to be the best option as 6-1 is just a painful map to clear even with a full deck team (I only managed to clear it in one go due to sheer luck).

6-2 is also painful but imo, a bit better than 6-1. 6-3 can be downright horror to farm if Katori only drop S-rank (pretty sure there's a farmable way).

You're aiming for Shoukaku so don't do that recipe. It's just a waste of resouce. I usually get her as byproduct while aiming for Taihou (but you already get Taihou...lucky you).

The bottom line is 'take your time'. Fall event shouldn't be that hard (I hope) so just take your time. I'm pretty sure you can manage the next event with what all the ships you have right now. (judging from just what ship you have alone).
