Lunar cycles for a two moon planet (one of which is smaller and orbits the first moon)

My planet, is roughly as big as Earth, but has two moons. The first moon, Luna, is essentially the same as Earth's moon, but the second, much, much smaller moon, Selene, actually orbits Luna. Selene is about the size of Ceres (it's a captured asteroid) and orbits at about (10,000-60,000) km from Luna.
So what would the lunar cycles look like in terms of length, and such? Taking into account the fact that Selene passes behind Luna. Secondly is this setup feasible at all?

Edit: Because of the Roche limit, the distance has now been changed to 10,000-60,000 km.
