To pull this off, you need to get someone other than Willy on the German throne, someone capable of continuing Bismarckian foreign policy long-term.
You don't specifically need a different Kaiser. In 1914, while still having important power, the Kaiser is far from the deciding factor in foreign policy. What you would need is someone who is a.) able to take charge of foreign policy and b.) smart enough to play the european alliance system at a time when the odds are somewhat badly stacked against Germany.
The question is, what can Germany offer Russia in an alliance?

Austria-Hungary and Russia had a lot of conflicts on the Balkans and Russia was a friend of Serbia.
That's not a necessity though. OTL Russia eventually choose Serbia as their Balkan "ally" over Bulgaria, but that might change.

In order to make both those powers allies, one would have to come up with an agreement on how to divide Balkan. I assume particularly Bosnia-Hercegovina would be a conflict area. I cannot really see how the Germans could ally with both Austria-Hungary and Russia at the same time. Both France and Britain saw Germany as a dangerous power. It was thefore probably totally unrealistic for Germany to become allied with more than one of the other big five. Only Russia and Austria-Hungary were possible allies and Germany could only pick one.
OTL, the Germans were reasonably close to getting into some kind of alliance with Britain (which of course would not have made any definitive commitments). It was torpedoed both by the influential germanophobe faction on the British side and the policy of the Germans to avoid a commitment that would constrain their freedom of movement, especially concerning colonies.
It is also not accurate to say that Britain and France were "afraid" of Germany. Britain, specifically, was more afraid of Russia and sought to avoid conflict with Russia by joining the Entente. France was not so much "afraid" as it was vengeful, though they of course realized they needed allies against Germany.

So, the question is if they picked the right one. And how would an alliance with Russia have influenced the course of an alternate WW1? Who would have won and what would the post-war map have looked like? Would Russia have faced revolution also with this alliance?
The thing is Germany did not "pick" an alliance. It had an alliance with both A-H and Russia and Russia slipped away. It wasn't part of a conscious foreign policy so much as lack of one. We'd need to look at what Germany could have done to keep Russia in the alliance, but I am not sure the Germans have any good arguments outside of somehow giving Russia the Straits.
Regarding WW1: If Russia is allied with Germany, there is no WW 1 as we know it. It only started OTL because everyone thought they could maybe win it. If Germany allies with Russia, everyone will see them as an unstoppable juggernaut. France in this scenario cannot afford to let a conflict with Germany escalate, and Germany itself isn't likely to start a war either, as they aren't concerned about being surrounded and the Russian buildup ITTL. That leaves us with an A-H without allies and more concerned with internal reform, and Britain which, as always, tries to stay out of trouble on the continent. Under these conditions, it's unlikely that an actual world war breaks out.
