The models would be in the client, not in DOL, all you have to do is guess the correct model number.
That said it won't work on every client, only on versions late enough to have the new models.
Remember that DOL does nothing except tell the client what to do.
Put this mob here and use this model, play this animation, make this mob walk, change this mobs health to this, etc.
If something is not available in the client the results are random, sometimes a client crash, sometimes you're holding a giant bag, sometimes a plain white block.
