In hindsight: I guess using the world's whimpiest powerhead's isn't such a good idea
I tried the 'corkscrew' idea, since I had to get my hands wet anyway. I'm sure a lot depends on the particulars, but I did get a nice boost (maybe 2x to 3x).
I had to use a small hammer to reattach the original rod ends - so that rod ain't moving!
I'm pretty please with the way my acrylic hack job went. I'm thinking about trimming off the end so that it's a little bit shorter, the next time I decide to get my hands wet. Maybe think of something clever to disguise it somehow. (Mount SPS corals on it?)
I guess the next bit of engineering would be how close to the body you can mount the prop and still get the best flow. In my specific case I don't really need to worry about fish or length - and it's probably a little longer (bigger) than it needs to be. My stubby props are mounted right next to the body - so while low performance they are small(er).
