If you're good with horror games, box_network is a medium-paced CitW-based jamjar with a fairly active metaplot! Obscure characters abound, and there's a pretty good pile of animu.

As far as castmates go, we've got an awesome Kyoko who I know would have fun playing off a Sayaka. I don't think we have much for your others, but honestly, everyone I know on your muselist looks great. Kudos for the Chrono Crusade ones especially; I didn't know anyone played from that series!
