Would the Soviet Union still emerge?

How does a successful Baltic operation affect the Soviet Union and the Russian Revolution?

The Soviet Union probably never forms because a supplied, victorious army preserves loyal regiments and blocks the conditions for a Bolshevik takeover, though a later moderate revolution remains possible.

A Russian army that remains supplied and shares in victory is not hollowed out like the historical wartime force. Loyal regiments survive and retain the capacity to resist a Bolshevik seizure of power. The prestige of victory also helps Nicholas II offset the memory of defeat in the Russo-Japanese War for at least several years. A later middle-class or Menshevik-style revolution remains possible because Russia's political problems do not disappear. The collapse that allowed the Bolsheviks to prevail during the historical war no longer occurs on the same terms. Reform or revolution follows a different timetable, without the Soviet state as it developed historically.
