Partial summons are fine. Weiss summoned a single arm of her knight at one point after all.

I'd reserve the elemental effects for dust interaction. So the skeleton is only on fire when he uses Fire Dust with his semblance. If you really want the fire effect to be there wihout Dust, then it  must  be a visual effect only. It does nothing but make it look cool until he adds dust. Otherwise it's doing too many different effects to really be counted as one semblance.
