SoGs can easily be replaced by Sancs, as the deck doesn't use light quanta, and they're useful against her anyways. As for the eternity, my first instinct is to replace the eternity/cat loop, rewind, one dragon, and the fire storm with a pair of quinted lava golems and a pandemonium. Pande is usually better than fire storm when you have only immortal creatures, and the changes as a whole spread the quanta around a bit and provide enough damage so an eternity loop may not be needed, which could be better unupped. Adding more cards in general is also an option.
Just theory though. We'll probably have to test it a bit and see how it goes.
