I will abandon all preconceptions and construct an integration based on the information presented in the game thus far and my knowledge of other hoyoverse games which is not absolute. Genshin literally begins with someone visually indistinguishable from HoV Kiana calling herself the sustainer of heavenly principles teleporting into Tevyat from what one must assume is the void/space outside of Tevyat. The primordial one is the god of humanity and the creator of humanity at least insofar as its relationship with Tevyat is concerned. The PO moreover is the entity that created the false sky surrounding Tevyat and by extension a new fate for life/mankind. Though they are distinct in Hi3 lore, the CoF represents the fate for all life not simply in one universe but across all universes. This is antagonistic toward the goal of the PO which is a new fate for mankind. Logically, if they were going to integrate stories, it would be revealed that Genshin is a universe subject to the assault of something like the CoF using HoV Kiana as a vessel to manifest its will, which is the fate for all life across all universes. The primordial one, however, is an entity that has successfully shielded mankind against their fate at the hands of the CoF or has created some kind of deal that was violated with Khaenriah and the summoning of the twins.

So the PO =/= the Sustainer =/= The Abyss and there are two different sets of laws that govern this universe: the laws that govern tevyat which represent a localized fate and the laws that govern the universe (and all universes) which are represented by Kiana and the CoF. The rest of Genshin's universe is dead space (a void), the CoV is waiting outside the bubble to subsume life on Tevyat, the PO has created a framework to prevent this, and the abyss represents some aspect of the imaginary tree/imaginary space energy being wielded by people that dont know it
