The Earth-moon is also quantized, with the same quantum numbers.

I'm not so sure. The quantization of the orbitals arises from quantum interference between successive orbital periods. There's no way this interference is going to happen in the earth-moon case because the earth and moon undergo irreversible changes on a time scale much shorter than the orbital period.
