Considering the social structure in Germania and the size of the tribes I'd more than doubt this. The big Germanic foederations at teh end of the Roman empire could field between 30.000 and 70.000 men at maximum and they were considered big. The lack of infrastructure and agriculture in Germania during the 1st century would make it impossible to feed such armies and Arminius didn't even have full support of his own tribe. I guess 15.000 for each of them would be much closer to reality than 150.000...or a strenght of 150.000 for both groups combined including women, children and old people.
