Spies like who?

A friend and I are planning to attend Costume-Con 28 next year, and we need to start working on our costumes soon. The theme is “spies.” I’m too tall for Boris and she’s too short for Natasha, and I’m not particulary interested in James Bond, or most other spy movies for that matter. So, I’m wondering what spies there are in anime worth considering. Let’s see: there’s Tenhou and Tenten from Oh! Edo Rocket, and Yomiko Readman and Drake Anderson from Read or Die (I don’t think I should ask my friend to be Nancy). I’m sure that there are others. What other pairs of spies are there?

Update: Are you a fansub team looking for a new project? Consider tracking down and translating the video of the stage play Oh! Edo Rocket. There are some brief excerpts here.
