We could always just play it simple by giving her the one multi-elemental attack, and one attack of each element individually, maybe with a matching status effect (Blind for Thunder, Slow or Stop for Ice, etc.)
While I applaud the creativity of your idea, I suspect it would be much easier to simply apply Shell with a Relic and cast Life 3, rather than dealing with the Freeze status.
I feel like Freeze would usually outweigh the benefits, even if we were to make it a full heal.
