I don't know if you can do it with keyclone but there are definitely ways. I've been waiting to try this for years but the product as it is right now would be frustrating to box. No follow command alone makes me lose interest. Manual aiming, and friendly fire combine to take away a lot of the playing styles you could use to box it.

It will be common to have a crafter alt account and a PVE or PVP character, or all 3. I don't see boxing like you see in EQ or WoW becoming too popular, playing even two characters would be a challenge.
