"It might also be helped with a well-placed capacitor or resistor in the crossover to roll off the highs a bit."
Actually it would be an inductor in series with the tweeter with a resistor in parallel with the inductor. However it will not change the character of the highs just the quantity. IME you can not deal with resonance peaks in the crossover you have to deal with them physically. IE blocking the offensive resonance, stiffen the dome or use a different shape and or material.
