I think the crowns are good to tie them all together yeah!

Outfits: Psii and AU Steve will be dressed in matching wheat suits. Sayaka will have a sherwani style grain colored dress and Daryl will match her. To tie the pairs together they will all be wearing these crowns.
Partners: Psii & AU Steve, Sayaka & Daryl
Attitudes: Sayaka and AU Steve will generally be surly and quiet.

How is this? I think I should wait for Psii and Daryl's players to give input for their attitudes, unless they will be the same way!
