It seems that Kekkei Moura is a type of Chakra that contains all 6 element fused together. Interestingly, this type of Chakra doesn't have a specific form, like advanced natures, rather it remains in the form of special Chakra.

It's just a first-rate Chakra, and everything used through this Chakra is considered Kekkei Moura. For example, Kaguya's KM Taijutsu is the same as the Gentle Fist's Hakke Kuushou, but unlike the Hyuuga who use normal Chakra, Kaguya used KM Chakra.
