Not a crossbow. Just a regular bow (reclusive or long). See the anon poster above, as he or she put it best. There are such things as metallic bows and they work perfectly fine. If a sheath can expand into a shield, it can compress and expand into a bow. It sounds like it could work fine to me.

And yes, we agree on the aura thing.
