Summary:  For every homogeneous Hilbertian operator space $H$, we construct a Hilbertian operator space $X$ such that every infinite dimensional subquotient $Y$ of $X$ is completely indecomposable, and fails the Operator Approximation Property, yet $H$ is completely finitely representable in $Y$. If $H$ satisfies certain conditions, we also prove that every completely bounded map on such $Y$ is a compact perturbation of a scalar.
