Not sure how a Spacial Doorway intended to banish/imprison low ranking Arrancars for eternity is supposed to shatter a compression of their power, let alone a part of themselves, even if its a sword. Don't even know this could be considered "logical" by Bleach standards, but I'm glad you're at least thinking outside the box, hehe

Through the devouring of Hollows and/or training one can become stronger. If you take a look at Nnoitra, it was obvious that he was granted Hogyoku powers during the time that Nelliel was Tres Espada. In the time of her absence, he managed to increase his strength through training, thus the change in shape of his Zanpakutou and most possibly the aesthetic change in his Ressureccion.

If you want a more inventive way for a Canon character to gain further power, while possibly leading to their untimely demise, here's my suggestion: Tear the rest of the mask off.

It sounds crazy, but really, the mask is a form of psychosis inhibitor. Its the remnants of the human heart that's clinging to their mind, making them what they are. If they strip away the rest of that, they can become something that is both Hollow and Shinigami. In that sense, they can truly become stronger beings, and develop their own abilities in which go along a path of their own choosing.

While there is vagueness to what I am suggesting, it is the best thing I can think of off the top of my head that's creative ^^;
