The basic, big problem with this strategy is that Germany already tried the Austro-Turkish alliance in OTL, and it badly failed in its time of trial. To be safe, Germany absolutely needs to pull either Britain or Russia in its alliance system (which shall also make Italy a reliable ally, a much less indispensable but still quite useful boon).
If Germany and Russia keep behaving like OTL, Anglo-Russian antagonism shall evolve in an anti-German alliance of convenience. To try and make Britain an ally, Germany needs to pull all stops and pay all prices to appease British fears of a German continental hegemony, and hope that Russia is sufficiently more aggressive and successful than OTL to make the British keep deeming it the biggest threat to their interests. This might or might not work, but there is no real guarantee that it shall. British paranoia of potential continental hegemons is notoriously difficult to appease for all time.
Alternatively, Germany needs to ditch the Austrians and Ottomans as allies, and make a strategic compact with Russia which is eventually aimed to partition the spoils of the decaying Habsburg and Ottoman empires. This is pretty much guaranteed to work if Germany makes an honest effort at it, and while it shall make Russia grow stronger, Germany shall do so as well (creation of Grossdeutchsland and stuff). Russia may or may not become too much aggressive and demanding for Germany's interests to bear down the line. If it does not, all good. If it does, then it would be much easier for Germany to switch to an alliance of convenience with Britain to contain former ally Russia than to do the opposite, if Russia really starts looking like a serious threat to the European order, given the way British foreign policy works.
To sum it up, OTL German alliance system was not enough to ensure Germany's safety, an alternative strategy that established a solid partnership with either Britain or Russia was needed, and while both alternatives were potentially feasible, the Russian alliance was easier to accomplish and manage.
