It's often best to try to avoid conditional construction with that syntax, it is much harder to interpret than the For - Use. Your scenario can be solved using:

        For<IDoStuffWithFooA>().Use<DoStuffWithFooA>().Ctor<IFoo>().Is<FooA>();
        For<IDoStuffWithFooB>().Use<DoStuffWithFooB>().Ctor<IFoo>().Is<FooB>();

        For<IFoo>().Use<FooZ>();

        Scan(
            s =>
            {
                s.TheCallingAssembly();
                s.WithDefaultConventions();
            });
