2nd floor bath – flooring question

Hello, we have an 1890s house that we’re renovating ourselves. The 2nd floor bathroom has 12″ ceramic tiles embedded into a mud floor about 3.5″ thick. We’re renovating the whole room, and while the tiles are in fine shape and the footprint of the fixtures isn’t changing, we’re not in love with the tile. We’d like to tile over the existing tile, but is the weight going to be too much, or can this thick floor take the weight? Do we need to tear out everything? Your advice is much appreciated, as always!
