Correct me if I'm wrong, but doesn't she live in the slightly less shittier parts of Europe? AND have a day job to boot? I think those would be the dealbreakers for joining Kevin's JP misadventure entourage. Iori could work if not for the fact that she doesn't live in Japan either, thus reducing availability.
So no, unless Fishman hires a JP staff member/talent who's both fluent in English AND can take a few days off to escort a crazy rich asian and his gaggle of sad girls around Akihabara, Clara would be the only option.
