Alternate Socialist Germany - Successful Spartacist Uprising in 1919

Diverging from OTL, I intend to ask what may happen if a timeline were to play out like so,
POD, 1916
- formation of the Spartacus League, Karl Liebknecht and Rosa Luxemburg associate more with the league in order to aid them in their struggles, more so than in OTL
1917ish, as the league prepares to arm its men, Germany military weaponry is some how smuggled to the league in order to prepare for a revolution
1918ish, the league begins to see a potential uprising date soon arrive, so instead the socialist factions of the Rhineland, Bavaria, Saxony, as well as Berlin and the surrounding region begin to secretly coordinate at meetings with Liebknecht finally becoming the leader of the revolution
January 1919, the Freikorps sent in to defeat the uprising troops are ambushed by prepared Spartacist troops in the Rhine, preventing the Freikorps from moving in from the west to siege Berlin, with the military being divided upon itself, as well as Germany suffering from the loss of world war 1, the seizure of Berlin is successful, and immediately at the same time, uprisings across Saxony, Eastern Germany, including parts of Pomerania and Silesia, as well as Bavaria and the Rhine occur simultaneously.
Spring of 1919, The Soviets begin attempting to aid the revolutionaries in their war, whilst the entente attempts to aid the Germans, however with the recent tensions of ww1, the west has difficulty in aiding the Germans. The Military is finally forced to involve itself, however as expected IOTL, the more leftist factions of the military begin to sympathize with the revolutionaries, maybe even turning their backs on the Weimar military, whilst the conservative factions begin more ruthless campaigns against the Spartacists, prompting lack of coordination and an internal collapse of the military. Much of industrial Germany is seized and revolutionary troops armed with the best Germany technology of the great war, while being backed by the Soviets, begin to move into less socialist regions of Germany, typically in the central and northern regions.
Winter 1919, A forced surrender from the Weimar republic due to being overwhelmed by revolutionaries leads to the establishment of a socialist government in Germany parallel to the early years of Bolshevik Russia. Liebknecht is appointed as Chancellor, whilst Luxemburg gains a high ranking position in the new Socialist Provisional German Government.
Early 1920, With Liebknecht as a Lenin-like figure in Germany, he attempts to warm relations with the Soviets, all while enacting reforms to make the state more totalitarian.
Not planned yet, waiting for responses.

The following map shows regions of Socialist-Spartacist influence/control in Germany around the time of the initial rebellion, the official border changes of the Treaty of Versailles had not gone into full effect, especially in this TL due to the internal struggle, therefore much of Europe is currently retaining their initial post ww1 borders for the time being. Will do a more detailed map in the future.
