Nope. The mass, charge (you forgot that one), and angular momentum of the black hole are merely the mass, charge, and angular momentum of the stuff that went into the black hole. You can't change any of the above from within the black hole - it's too late. As such, there's no "information" to be gained; an observer from the outside already could have figured out what the mass, charge, and A.M. of the black hole were if they knew what went into it.
