I think its been done before mate.
In the sense that we all have done it when practicing the diving board double.
It is a mistake rather than a well structured flourish.
Your comment about wanting it to be original to get it online, to have something against your name, to make a tutorial etc .... is just the wrong idea.
When you have it down, and it looks good, and you hit it 100% of the time, then show some people, maybe add it in a video.
Ideas will come to you over time. Some of the best effects are by the older generations.
So keep practicing, and forget about getting yourself a name, until you have got yourself an idea.
