I personally doubt that a Soviet victory in Warsaw would have changed much outside Poland. The revolution in Germany had already been crushed by the Freikorps and the Social-Democrats, while any serious threat against the state's political stability had been eliminated, after the failure of the Kapp Putsch. In Hungary, the communists had also been overthrown after the Romanian invasion, although there's a strong chance that their regime would have imploded anyway. Considering all these recent blows the communist movement received in Poland's neighbors, the revolutionaries had no time to recover, to make any Soviet intervention worthwhile. Meanwhile, the Soviet Union was simply too exhausted, after years of fighting off the Whites and foreign armies, to effectively invade other countries and install friendly new governments. That is apparent by how easily the Soviets were defeated in Poland, despite their early successes. In that war, the Soviets had initially high morale, due to the fact that many regions, where Poles were an ethnic minority were included in the Polish state, while the alliance with reactionaries, like Peltura, threatened even the existence of the communist establishment. Given the bias of the Czarist authorities, the map is definitely not 100% accurate, but the fact remains that Poland had annexed some clearly not very Polish territories. However, the leadership, influenced by her triumph, became greedy and continued to push for advance, despite Polish peace proposals, which resulted in the battle of Warsaw. However, as I said, the war was initially of defensive nature, which might be what encouraged the Soviets to attack, in order to expand their sphere of influence. Inevitably, the outcome of the war didn't change much, but even if the opposite happened, still nothing really important would have changed, in my opinion. Even the Jewish community, which was in danger of extinction, in case of Peltura prevailing in the conflict, since his factions was mainly busy with pogroms and massacres, eventually evaporated, during World War II, "thanks" to the efforts of the German occupiers and their Ukrainian collaborators.
