You could make a radioplay.. but you'd need an actual anime show for a fandub.. you could easily just re-write a script...

A voice actor (or voice artist) is a person who provides voices for animation (including animated feature films, television series, animated shorts), radio and television commercials, audio dramas, dubbed foreign language films, video games, puppet shows, and amusement rides. The Japanese term for a voice actor is a seiyuu. When singing is called for a role, a second voice actor is sometimes cast as the character's singing voice.

In a live-action production, voice actors may be called upon to read the parts of computer programs (Douglas Rain; Majel Barrett), radio dispatchers (Shaaron Claridge), or characters we never actually see on a show who give instructions by telephone (John Forsythe in Charlie's Angels) or mailed recording (Bob Johnson in Mission: Impossible).

It is not unusual to find amongst the ranks of voice actors people who also act in live-action film or television, or on the stage. For those actors, voice acting has the advantage of offering acting work without having to bother with makeup, costuming, lighting, and so on.
