Unfortunately, doing that is basically grounds for instantaneous unmaking, owing to the whole Decibitus-After shenanigans. Papi can probably offer you alternatives though.

Simplest way of doing it would be to just have magical summons in the shape of animals, without actually doing the whole 'soul-binding' thing. That's basically in line with what Ed does, where his undead are just magically-animated bones, rather than living souls jammed into a new vessel or spirits bound to his will.
