I probably should add to my prior post is that the reason behind this hybrid not making a commercial production at the SA fish farms may have another explanation alternative and/or additional to poor viability, which is the poor carcass yield Cliff mentions, that is it doesn't grow fast enough and big enough to be successfully marketable. So a chance remains that this hybrid might be more or less viable. I don't think we know why it hasn't been commercialized, if anyone knew, it'd be Cliff.
Synodontis have been hybridized so much for purely ornamental fish trade and the main driving force I believe was and remains profits. Their goal appears to be to create hybrids (cheaply) that resemble genuine syno species as close as possible.

not criticizing you but trying to understand: but your avatar is a manmade hybrid fish, a blood parrot, is it not?
