I had a similiar theory time ago, I had explained Mei unability to use a Kekkei Tota with her actually being some kind of experiment in trying to recreate a Kekkei Tota user, that of course sort of failed. As far as we know there's a Lava user on Onoki's family (his Grandaughter, theorizing she did receive the Lava Release from her Grandfather (from Mother part?) so that may add to the probability of it being a result of selective breeding ( by stopping it, the gene stop appearing ) Onoki's and Mu hand take on a peculiar shape while using the dust release: a triangle. Imagine the vertexs taking on a different nature and you have three-nature mixing. Why didn't he use his other natures? Well, I supposed Dust was like Lava+Explosion time ago since the explosion release is inferior to dust on almost all points ( range, power, adaptability, controllability ). But it may be the same with like Magnet and Lava: the Dust release still has a whole deal of power the magnet release hasn't, same on the lava part, it lack controllability on most of it. Another explanation is that Tota users may somehow lose access to the other Genkai they have and/or they need to know a certain secret to find how to use it.
