Allegro doesn't have a way to manage models so it is not possible.

Remember that Allegro isn't a game engine.

Yes, you can. You need make a tool for convert the model and animation in something more, like a mesh in opengl, and something that can take the control of animations.

There was someone here who had done it, but I don't remember what his name was.

Assimp (https://github.com/assimp/assimp) is pretty straightforward. I use it in my game to import models from Blender. It's like a couple hundred lines of code to convert from Assimp's data structures to something that fits into my game.
