Any tips on how to get a good launch for this new move i'm making?

Here are a couple replays of me slightly pulling it off

The Idea:
I want to get onto one knee and launch into a corkscrew( Will be called Half Sword) and the other to get on my knee and launch into Jack knife or dis bullshit but do the spins while in the air( Will be called Full Sword) any tips on how to pull it off?

The Replays:
They are both Full Sword variants cuz i havent mastered it yet, Half Sword Alpha is the better one, tested is where i got the idea from. I basically want to get what i did in the half sword alpha into a standalone version to offer up to the toribash tricktionary >.<
