Probably not: the Yozi's system works due to their connection with demons and the fact that they have invested part of themselves into Lillun. It's more possible for a Sidereal to be able to do what the Deathlords do, but that probably requires binding your hun soul to part of the Neverborn, which invovles killing yourself (thus no longer a Sidereal) and, well, becoming a deathlord. Oh, and dedicating yourself to the cause of the Neverborn. After all, the Neverborn can take away the ability for the Deathlords to exalt people.
It's more resonable for a Sidereal to pull a Jade Prison mark 2, though that should be hilariously difficult.
Honestly, I think getting a Monstrance is the easiest way to do it. You simply need to find an Abyssal capable of learning Call the Black Sun and get them to cast it for you. Then, you can take the Monstrance, trap a Solar inside it, and then kill them. Voila, you have an captured Exaltation!
Now, this is still very difficult, but I think it is not on the same level as the other options. And looking at the lore, the orginal Monstrance was explicitly designed to allow it's maker (also the bearer of the Exaltation) to cause a specific mortal to exalt. Now, it had obviously gone through some design changes since then, but I would give it a reasonable chance at working.
