Sorry for the late reply. I don't think this is possible right now. I remember I wanted to add the ability to define nested structs (by making struct.Struct a subclass of types.CType or something along those lines) but never implemented it.

As long as you don't have an array of A you should be OK just copying in the definition of A into the appropriate place in B?
