I know that CC are considered to be higher end predators, but my limited experience with CC is that their mouth-gape seem to be on the smaller side compared relatively to the overall fish size. Theos did a long study on it maybe a decade or more ago...'cause he's older.
Further, when I observe many CC taking feed, they just seem be highly inefficient and slow moving. Now, I have seen a few with the "Hoover" technique, as in vacuum cleaner; those ones are highly efficient but still slower.
I think there's no reason not to try if it's what you want to do.
