Not necessarily just a swap.

An individual driver's electrical characteristics (resistance and impedance) as well as its acoustic properties (efficiency and sound pressure level) are figured into the crossover design. Unless you find a suitable replacement mid with the same parameters as the original, you're going to probably exacerbate any existing problems further. What might be a simple and direct solution would be to insert a one or two ohm, 10 or 25 watt resistor in series with the mid range to attenuate its output slightly. Using additional resistors in this way will alter the crossover point to some degree, but probably not enough to notice. Otherwise, if you replace the mid as you originally proposed, it's a certainty you'll have to modify the crossover to some degree.
