The only problem is for these to be reconstructed after being destroyed, there would need to be at least some shred of them left, or else they would just be considered techniques. If you're creating something out of nothing with your plant abilities, it'd be a technique. As long as there is like a patch of the cape, you can recreate it, etc. Just so that's clear.
They're approved but you can't "make" them until you're Jonin+
Unless you got some weird Naito hax from Dipu, which you probably did....
