Functional dependencies don't work in my case. Actually, I don't see why

Ah well, it's cruel to say that without explaining to us why!
I'm not sure why a complete cyclic dep a -> b -> c -> d -> a isn't what
you want.
What seems to be needed here is a type class construct with a kind of
record parameter so that instance conflicts cannot occur.
I'm not entirely sure what you intend to mean by this, but if you mean
what I guess you mean:
class Java (a,b,c,d) where ....
then I think that would appear to be the same thing as a complete cyclic
fundep to me...
