Without Kabuto, Tobi would never create Juubi as he didn't have Kyuubi's chakra (Kin Gin bros).
SO it would end as:
Whole shinobi alliance (with Kages) vs Obito with Gedo Mazo (there would be no bijuus as there would be no hosts for them)
And this fight would be easily lost by Obito. Quick strategy from Shikaku and baam war is over.
