Maybe I'm overthinking this...but why would staking be necessary?
The staking on an AR is to prevent the tube from backing out and causing a malfunction with the buffer and spring during firing.
Since the the AK platform operates differently, the tube rotating slightly isnt a big deal and wont cause the rifle to malfunction.
I would bet if you were really concerned with it, blue loctite would suffice to keep the tube from rotating.
I've never owned anything by Stormwerkz, but I've used their stuff on other people's rifles before, and never seen or heard of an issue with it. I dont see it having any problems on your Draco.
IIRC, @Finslayer83 used a Stormwerkz hinge on his Draco SBR.
