Germany even in defeat exited WW1 as the strongest power in Europe, except restrained in various ways - limits to its military forces, economic reparations, territorial losses, political restrictions on alliances - by the Versailles treaty. If Germany had won the war, it would have had no limits to its military forces, it would have been receiving reparations from the defeated powers, it would have no limits on its political alliances and it would have gained territory, not lost it.
I agree that the CP were going to dominate if Britain remained neutral. That's why there was no chance Britain would remain neutral - they were going to war with Germany if France did, and the actual facts of the Franco-German rupture did not matter. This is why Moltke asked for and received the automatic permission to violate Belgian neutrality. Because the dice were already cast, and had Germany gone east as you envision, the British would have allied with France and the front would be established at Aachen, with Belgium dragged in on the side of the Entente just like Greece was dragged into the war by the Entente against its will.
If Britain - meaning a small cabal of Grey, Asquith, the King and a few other insiders - had wanted neutrality, this hardly required allowing Germany to steamroll Russia to get it. The Germans asked for Britain to help them hold the ring between Austria and Serbia. London could have done that. Think of this. Instead of an Austrian note on the 23rd, three separate but identically worded notes, one from Austria, one from Germany, one from Britain. The notes are the 10 demands of the Austrian ultimatum, except the demands are from three countries, not one. Serbia must accept unconditionally. There is no war.
