I think you need to ask yourself if you "need" to use these specific moves that were created by others in order to have a new effect. If you can eliminate those moves and substitute them for more common moves, moves that have been around long enough that they are basically public domain, and you still have a new effect, then...you have a new effect! If using these moves, by other creators merely, makes another pre-existing effect better, then all you have is a nice twist on an old effect.
So for instance, there is an effect I do called "Throwing Star." (it's unpublished but I feel safe in calling it my own effect) In that effect I use a Losing control(Lee Asher) and Earnest Earick's version of the convincing control. I can eliminate those two moves and replace them with more common controls and the effect is still unique. Thus, it's mine. (provided someone doesn't reverse engineer it and rush to publish before I do!
) I also have (as do most card magicians) an ACR that is pretty unique to me. The ACR includes a Silver Surfer, a commonly used sandwich effect, a Gravaty Half Pass, and a slight modification to Ben Earl's Stroke Change. Were I to swap the Silver Surfer for a double under cut, the Gravity Half Pass for a standard half pass, and the Stroke Change for an Erdnase Change, the ACR would be a pretty common, run of the mill, ACR. Thus, though it is one of my favorite routines, I would never think of publishing it.
So, do the same process with this effect you are talking about. Replace the moves you are currently using with more common varieties of those moves and ask yourself if your effect is something new.
