So you're suggesting
1 Prince, 1 VS, 2 Aurora
4 Hemlock + 1 Aconite + 1 Hellebore
4 Nightshade + 1 Aconite + 1 Hellebore?
I was more dubious about the Aconite in the nightshade squad, doesn't seem like they really need to be able to drop shields reliably to do damage. the Hemlocks need to be able to connect with those lances to be effective, so the battery makes sense. I was also considering running two Solaris instead of Auroras and run them with the escorts instead of the VS.
