Club championship of the CIS countries.

But still, which version will be played in the final, if it even takes place???? I consider this question one of the most important.

The most important thing is that the qualifying tournaments take place; otherwise, we'll just end up talking about it.
As for the version—the layout can already be read: Michurinsk - SoD, Kyiv - SoD, St. Petersburg - TE, Yekaterinburg - TE, Moscow - likely SoD, Minsk - likely TE.
Provided that Moscow and Minsk organize their tournaments.

Therefore, I would suggest TE-lite: not quite TE, though not SoD either. But both SoD and TE players can play it with roughly equal success. But first—determine the organizers; for example, if only Michurinsk, Moscow, and Kyiv hold tournaments, why should we play on TE? And vice versa.
TE-lite—only if all the main communities, all three resources, participate. As a compromise acceptable to everyone.
