Quote - Did the OP suggest that he was building the figure for any program other than POSER?

Yes, the op did, depending on how you look at it.

((2D rendered characters in a 3D space.))

That is why I asked about what it was going to be rendered in, triangles, etc... A transparnet png sequence can be just as costly memory wise as coding the game to use the wireframe. It also presents issues with lighting, shadows, etc. The lighting in the game will be fixed to the lighting in the sprite renders for the most part. Camera issues crop up as well. You are not going to be able to pan to the side, as an example. This can cause problems depending on how the level is set up, and the OP did say it was a 3D level.

There is nothing wrong with doing it sprite based, I was just trying to clarify if that is what the OP is doing. Doing it that way does limit the amount of animation that can be included before it uses more memory than a wireframe rigged in Unity or any other game engine would.

Now that I know that it will be sprite based the only other question would be, if that is the way to go to conserve file sizes. And if the levels will support it in every senario.

Without knowing what the OP has in mind for the game scene and play wise, there is no way to answer that from the information given. We already know the OP uses both Poser and Unity, so one would assume that they are experienced at both.

Many times what starts out as a sprite based game, ends up being nothing more than a story board full a full fledged game due to the limitations sprite based presents.
