No "replacement" required, just change your character picture.

just change their picture to a human

This is not how it works. This is not how any of these work.

The most fatal issue is that a lot of roleplay would be going to be retconned. And I mean it. Ask SirDoge and Wellingtons how much roleplay they had put into doing things out with me - it was not only initiative of mine, mind you. Not to mention several other players (these know about whom I talking about) which enjoyed such a roleplay of human-animal hybrid. I heeded the criticism on how such a character should work.

Problem with Cody is not 'duh, you can just change the avatar'. Human Cody will not be the very same Cody created previously. It means a lot of changes, a lot of stance and behaviourism changes - it is easier to create whole character a new than to do a lot of retconning to already existing character.

For me, both possibilities is throwing my efforts into dustbin.
