There are a lot of reason to think a nymph like this would be effective, no hard steel backbone to start off with, increase moment of the body, adding a disc perpendicular to the hook shank might add even more action against retrieval or current. My my old slick skull this does not appear to be easier than a typical nymph however, actually a little more difficult. I do like your mad scientist mind however, "It's alive, it's alive!!!"
