I like the idea but i don't think you're understanding wat a safe jump is.
a safe jump is a confirmable jump in off a hkd that allows blocking to be possible by either
A) using your jump in attack as a meaty, causing a wake up to whiff due to its start up.
B) jumping in from an angle that would cause a wake up to whiff.
Due to this games mechanisms on wake up I don't think true safe jumps are possible. I see these set ups as jump in reversal baits.
Still, good find and continue labbing it up.
Also, a true safe jump will force your opponent to block your jump in, if they choose not to reversal.
