Error Sign Alternative?

For my server I’d like to have lots of player models in the pointshop, but it can be really annoying for new players to download. What I’d like to do is have a pack of the models available for people to download and have it so that those models will show up as a default one rather than an error sign if people don’t have them. If I just replace the error sign model with one of the default models will that work or will they have no animations or something?
