Good on ya for being curious and asking questions. Bucket finds trolling to be a form of entertainment (which I believe is a common motivation for many trolls) and interactions like this boring.
I am not sure how your idea of a secondary blade would work out. If you know someone who can adapt an oar that way and have the money give it a shot. It might be beneficial or it might not, who knows. I personally don't have the cash to adapt a perfectly good piece of equipment in that experimental fashion.
That said, what you describe as far as using the primary blade to reduce flipping might be feasible. In sea kayaking you can do a brace that behaves in a similar way and it can be a powerful move on a narrow craft. Ideally it wouldn't be as necessary as squaring up to features is my first choice. I suppose you could try and brace in the moment, though I would likely continue to focus on correcting the angle of my craft. You would also have to consider the violence of a fixed pivot point like an oar compared to a paddle. I can imagine that oar would likely want to shoot straight into the rowers compartment at that angle (broadside) and with the type of features that would flip a raft. Other considerations are where the raft is in relation to the feature: crest, approaching the trough, nader, etc.
