Again hard to say as I doubt Poland or the Baltic states had much love for the Russians but as Lljadw pointed out German attrocities didnt win a hell of a lot of friends with the locals either.
There were however a number of pro-German states occupied by the Russians that German troops could have been used.
The other thing is that I doubt the German divisions would have in German uniform as evidenced by their use of US uniforms while working for the allies immediately after the war.
The pro-German states were German allies ( Hungary, Romania ) and the opinion in the West was that they deserved what they got =that they deserved a Russian occupation .
In the Percentages Agreement of October 1944, Churchill proposed the following to Stalin : the USSR would have the following
Romania : 90/100% influence
Bulgaria : 75/80 %
Hungary : 50/80 %
Yugoslavia : 50 %
Greece : 10 %
Thus : why would Churchill fight to conquer what he gave away to Stalin ?
Romania, Bulgaria, Hungary were responsible for countless allied deaths,thus there was no reason to fight to liberate them from the Soviets .
And, 25 years later, Ceaucescu was received in Washington as an ally .
