Some advices on how to reduce the size of 3D Tiles datasets are provided by iTowns developers here.
It has been tested on a tile of one of our datasets (see this discussion) and allows to greatly decrease the tiles size (from 1.1Mo to 28.5Ko on one tile)
If at some point the tiles sizes becomes critical, we might want to take a look at this.
