Honestly, I wouldn't go with any of the options, except for maybe Orihime &/or Uruhara from Bleach. They're the only characters from the show I like. (Orihime is adorable in the first season, and Uruhara is just cool).
If I could throw out any random series, I'd go with Ranma 1/2. It's a classic, really funny, lots of pairing options, and it's really funny.
