Don't jump on my ass, this is just wishful thinking.
Based on Chapter 1007, it is reasonable to say and I am fairly confident Vegapunk did not want to give his "failed" Devil Fruit to the World Government.
I don't know if Momonosuke can swim/handle water. If he can, please feel free to show panel/episode. But, what if Vegapunk has his own stash of Artificial Devil Fruits that work just as real Devil Fruits.
Except in the case of these fruits, the weaknesses have been eliminated and the Water Dangers aren't there. If that's the case, that's a relative strong and free Power Ups that could be given to any of the strawhats should the time come where they may meet Vegapunk. It could be strictly Zoans. Or even Logia's and Paramecia's.
I just wanna see my guy Franky, and Nami get some busted Devil Fruits.
Maybe Franky finally gets a real Laser DF. Or Nami gets the real Goro Goro No Mi as the final Power Up against Stussy.
