Rapsitie Street Kids: “A Bunny’s Tale” lost 2003 Easter spec

Well it's not the very first step, a script would come before voice acting, and before a script, concepts would be tossed around (artwork, ideas). A script could have been written, especially since they advertise the sequel at the end of the first movie.

But with all of that being said, I sorta think these projects were done in a disorganized fashion and I wouldn't be surprised if they were like "let's do a Easter one" and then had no concrete plans for it. All we know is that it involved the Easter Bunny, which means there could be art of the bunny, maybe even an animation model (in 3D you don't need to wait for voice work to create and rig a model).

Edit: By create a model and rig, understand I don't mean animate. Just basically setting up 3D model to be animated. Although I don't know how good quality the lip syncing was in Rapsitie Street Kids was, and again I just think the production was a mess, so I wouldn't be surprised if they did things in a weird order. Also I don't know if there's any proof of concept, just saying it's possible.
