Is it possible to make a 3D/2D hybrid?

[anc]

I was wondering, is it possible to make a 3D/2D hybrid with Platinum Arts? Something like Final Fantasy tactics, with 3D terrain and 2D characters.

Best regards

Hm, I took a look at Final Fantasy tactics. It uses an isometric perspective to fake 3D.
You could do it (e.g. have a model plane the 2D sprites are assigned to), but not out of the isometric view (without modifying the engine itself). There is a sidescrolling mode and a FPS and RPG mode. Both are first person and third person. You can change the height by changing the dimensions of the bounding box of the players model.
Besides, why should you want to do a 2D game with a 3D engine? If it is because of your lack of modeling skills, go ahead and search for a modeler, learn modeling yourself or use free models (e.g. from blendswap.com or opengameart.org).

It's a conscious choice of art-style.

Sandbox doesn't do sprites at present, and billboards don't really exist outside of the particle renderer.
Sandbox isn't really a good fit for such a game
