Somewhat, yeah, until a player is actually nearby and it’ll turn into a physical ped.
That’s a curious use case, definitely, however, and currently I don’t think the RPC SET_ENTITY_COORDS is suited for that: it’ll likely need real node-based write overrides to do so. 
It’s good to see people finally try to write server-side logic, so we finally know what use cases people have and what to enhance. It’s been a bit hard to get a conclusive set of useful functions without anyone making use of the existing functionality!
Path node formats are generally documented, I believe.
