I need more information about why C and B need to be independent
types. Perhaps you can just do:

A -> BC -> D 

Basically, you've drawn a diagram that can't be implmented in Ada, and
asked how to implement it. The only solution is to give more
information about the real problem, so we can suggest how to modify
the diagram so it can be implemented.
