Yeah, having tha actual repellers/propulsors be both lightweight and more or less arbitrary shape could enable quite some nifty designs! Also as you just need

Yeah, having tha actual repellers/propulsors be both lightweight and more or less arbitrary shape could enable quite some nifty designs! Also as you just need pressurized Gass in the manifold for the thing to fly I wonder if an emergency system with a pressure bottle or even gas generator could be used to give you say 30 seconds of flight time needed for safe emergency landing if your pressure generating engine fails. Not to mention making it easier to combine two or more independent engines to feed the manifold for redundancy without the crazy complicated and heavy gearing V22 has to achieve that, as mention above.
