The embedding of SU(k)HC composite schemes within flavor-chiral color-asymptotically-free SU(N) grand unifying theories is examined. It is shown that unless k=3, the associated spectator-composite structure conspires to be real under the residual gauge interactions. The exceptional n-preon SU(3)HC scheme is capable of supporting a nonexotic quark/lepton spectrum only if n=4, 5. The SU(8)-embeddable n=5 case leads to a multigenerational Georgi-Glashow SU(5) picture.
