It is worth grinding Maya first then. AACI really helps and since you are pretty close to 75 anyway.

Also Maya is highly recommended for E7.

Shigure is worse than Aynamai in the long run. Although 10 luck give her better chance to active CI attack, Ayanami has much higher firepower + Tropedo stats, meaning her CI will do more damage.

In the long run, Luck can be increased by using Maryuu. While there is nothing you can do to improve firepower+tropedo.

But shigure is a fine replacment for Aynamai is this case.
