Iskandar Ishmael is amazing, but it will seem very out of place with Crispin Yew, Imogen Solace and Mab Margaret.
I think Basil Ishamel is doable, and Ernest Wythe too, but it's too serious and somber in my opinion. Mab, Imogen and Crispin are all playful. I like Vincent Elwood, Vincent Lucien and Vincent Xavier the most.
Thanks Otter. Good point about keeping the playful through-line.. Well, I don't know. At least Vincent is a good option, and I certainly have no time-pressure here, unless my dream was prophetic (gulp.)
