At minimum tho getting everyone to agree on current Territory is now Russian seems achieveable with current means.
That would be a failure for Russia.
1)Everything that does not include Kharkov, Nikolaev and Odessa (and ideally also Dnepropetrovsk region, also to have more control over the Dnepr and rebuild the dam) is a loss for Russia.
2) At minimum, the win condition should be for Russia to get all of them plus all of left bank (east of Dnepr) Ukraine plus Kiev region.
3) Real win condition for Russia should be to get all of 404 as Russian territory, including the north west as either russian regions or as russian protectorate (Puerto Rico style.
As far as international recognition, or everyone to agree, it is useless. Some countries do not recognise the English occupation of the Malvinas, but the only thing that counts is the defacto rule.
Russia should not make any concession in order to have its new south western borders (actually old pre-1992 south western borders) accepted by unfriendly nations.
As far as what is needed, yes numerical superiority is needed for massive advances, but such advances are also extremely costly in term of human losses.
Currently Ukraine is losing between 1000 and 2000 men per day, I do not believe the situation is sustainable for them.
Having the kind of numerical superiority you want will need also to remove many men from their work and their families, and could create more problem for Russia than the advantages it would create.
Furthermore, all of these people would need to be properly equipped, otherwise they will be not much different from the Ukrainian cannon fodder being removed daily from 404 streets.
In addition, there is a stable influss of new russian volunteers, which will probably amount to at least a couple of hundred thousand net increase of boots on the ground each year. And Russia has already to provide good equipment for more of them
