That would be so awesome if what you are predicting is true!
Here’s a link to the thread about that motor (For those who may not have seen it):
The thing I liked most about the Mad props is they look like what you described:

We seem to all agree that a larger prop is more efficient. We don’t want larger props though but the best way to imitate a larger prop is to have a large taper.
So who wants to be the guinea pig to test the m17 motor with the Mad Fluxer or similar propeller? I would make the investment if I was guaranteed to get even half of what you are predicting in return.
