While the idea is a noble one, this is not going to be a viable option. Let's look at the opening negotiating positions. Russia wants the effective end of Ukraine as a sovereign state. Ukraine... doesn't. Well, so much for finding compromise there. The goal of war is to make the situation such that one side realizes it can't achieve its political aims. Here again, both sides have reasons to be hopeful. From Russia's perspective, an operation that wins successful control of much of the country would hopefully make Ukraine realize that its existence as a sovereign state is already de facto impossible, so it might as well commit to that in a peace treaty. But Ukraine can point out that the war has not been going well for Russia, and the longer the war drags on, the less likely Russia will be able to reach that culminating point. Wars can simmer on for decades without concluding if things stalemate--the Korean War is 70 years long without a peace treaty and still ticking. If your concern is that nuclear weapons would be involved, then this initiative is even more useless. There is no geopolitical reason for Russia to be firing nukes (and NATO isn't going to militarily intervene in large part to avoid giving anybody a reason to fire nukes), so if those start coming, Russia is already not acting with concern for geopolitics, so the foremost geopolitical expert is utterly useless here.
