Does the name Spirit Wallace sound okay to you (for a newborn girl)?

One of my cousins is planning to name her newborn girl child that. While I appreciate the innate beauty of that name, there are some in the old family who are rooting for traditional names like Martha or Margaret over the "free spirited" sounding ones. My cousin loves giving her kids names from nature and mysticism. She earlier named her son Jupiter Wallace (age 5 now) and her older daughter Emerald Wallace (age 8).
