Good question and I have my opinion on that.... the answer is: NO. The only way to mix 4+ natures is Six Paths Senjutsu.

I think an elemental/nature transformation Kekkei Tota has to be a mix of 2 nature transformation Kekkei Genkai that share together 1 nature, so 4 natures Kekkei Tota isn't possible. My reasoning for believeing so is Yamato's explanation of his Wood Release. Earth chakra in one hand, Water chakra in the other hand, hands clasp together, Earth chakra mixes with Water chakra, Wood chakra gets produced, Wood Release technique can be executed.

Onoki too clasps his hands together while using Dust Release and he has only 2 hands last time I checked, which means there has to be only 1 type of chakra in each hand.

I imagine it like this. Earth in Onoki's left hand, Fire in Onoki's right hand, clasp, Lava Release chakra is produced, just like in case of Yamato. But then one of them gets exchanged into Wind and mixed with the common nature as well. Then Onoki just puts Lava Release into one hand while the other advanced/combined nature into the other and with the hands still being clasped, mixes them, pulls his hands apart and what don't you know... Dust Release has formed.
