The efforts of Roy-Sridhar-Close-Cho-Wise-Trivedi to resolve the CDF $\psi'$ anomaly with cascades from above-threshold $\chi^\prime_c$ states require well defined signature states require well defined signatures [a small total width and a large branching fraction for $\cp \ra \gamma + \pp]$ for the solution to be viable. Here we estimte the production of such states from $BR (B \ra \cp + X)BR (\cp \ra \gamma \pp)$ and $\gamma \gamma$ production of $\chi^\prime_{c2}$ at CLEO II, and comment on the feasbility of testing the hypothesis in terms of current experimental capabilities.
