I doubt it.

For one thing we don't even know if it is a Demon, or some other kind of monster or maybe just something inanimate that is temporarily turned into something living by Mard's powers.

On top Mira was unable to take Sayla over, except for one part of her power, so I doubt she could take over something that big.
