Concern for the mass of the potting medium is well founded. Going larger in pot size is going to increase the mass, and certainly going to a deeper pot is making it much worse. If you leave it as it is for now, my preference, and just move it up a pot size next year with butting the back end of the root ball against the side of the new pot and filling around the front end of the root ball with similar mix, you will probably have a good combination, as the plant will have more roots by then to help dry the pot out. When you finally do a thorough repot, you will want to remove very old bulbs to help with fitting the plant into the pot, or to divide the plant.
