It's basically just a different soul in a human body, and apparently it's difficult to tag multiple in a single body. Madara however couldn't become Juubi Jinchuriki while an Edo Tensei.

The Juubi is an even bigger mass that creates even bigger problems (e.g. Obito couldn't phase, as his ability is limited in volume and the Juubi -even sealed- breaks that limited volume), so it seems logical to me that you can't just become Juubi Jinchurki as even Kurama brings problems and the Juubi's far beyond that.
