I think in terms of realism we should leave as is. The SS-N-27 ASW is more effective and my preferred loadout. If we get into second guessing possible loadouts we could stray off into Dangerous grounds.
The Akula is pretty capable and in the right hands has no problems with a Seawolf.
Probably the best thing to do is make the 53 cm a UGST as that is almost as good as an ADCAP.
