The challenges are significant. I don't think that Russia will yield much on territory. That's why this conflict is happening, why all the lives and resources were sacrificed. Perhaps they will concede unconquered territory. I don't know how Russia define the areas they consider to be ethnically Russian, which would give some hint about what they would be willing to accept.
