I doubt that. It would be extremely expensive to re-build every destroyed city and pointless anyway since there is not population to settle all of them anyway. It would take billions dollars and some decades even to re-build St. Petersburg and Moscow.
Consequently, reconstruction will probably start with, essentially, tourist traps. The Kremlin and St. Basil's are likely to be rebuilt, once the cities are safe for habitation, as are some of the palaces of Petrograd (to house the art recovered from the vault, naturally). Some of the more famous Orthodox monasteries and churches elsewhere will follow.
However, the scale of the devastation is something worth considering. Even IOTL, there remain many ruined buildings from the Second World War scattered in city centers across Germany and Poland. Warsaw, technically,
still hasn't been fully restored, and it benefited from actually getting a substantial chunk of investment from two governments strongly invested in the impression of legitimacy the city granted--and even then the Communist government initially proposed just leaving the city unrebuilt as a memorial. Moscow and Petrograd and the other big cities have all those problems
plus NBC weapon remediation, and no pressing geopolitical need for the West to help them. Why bother with a Marshall Plan for a broken enemy that even China stopped bothering with?
So, who's paying for it? The Tsarist state has little money and will largely be depending on UNESCO stipends and aid packages from the US and EU, the latter of which are probably more interested in paying for vaccination and education among survivors to keep them from turning into a refugee crisis/disease reservoir. The FEK and Siberia have advantageous ties with China, but might not be inclined to help pay for reconstruction. Ukraine and Belarus and the Balts will range from indifferent to actively hostile to sending EU money east--and demand from Novgorod extraordinary concessions (probably in the form of gas pipeline deals) for their votes European institutions in its favor. There will also probably be a strong dependence on remittances from any refugees/immigrants who aren't too bitter to send a few euros 'home.'
There is a further complication, in that wartime devastation has also probably wrecked the rail and road networks that would be used to distribute aid. This has two consequences: first, that the surviving population will cluster close to the western frontiers or the surviving ports along the north, since large parts of the interior country will be functionally inaccessible. This will make it easier to distribute aid to the people, but will massively reduce the priority of reconstruction outside the parts nearest to the frontiers.
Well, actually, a third consequence: the famine won't stop when the war does.
