That would only work if Lucy has equal or more magical power than Minerva, which might be possible between her training with Capricorn and second origin, but we don't really know.

It would also require Lucy (or rather Gemini) close to Minerva, which is a bit of a problem with an enemy who can just teleport both herself and the enemy around.
