Sometimes the best inventions come from those whom you least expect anything at all from.
I know about as much about a paragliding wing as Hedy Lamarr maybe knew at first about radio waves.
That being said...
I'm not saying go out and start sliding in "off the shelf" fiberglass tent poles willy-nilly into sleves you sew into your paraglider wing.
But they are a good visual example of an widely familiar idea that is light weight, springy and flexible, and can be broken down quickly into a compact package that can fit in a bundle. Anyone who's ever set up a modern personal tent is familiar with the fiberglass sticks I'm talking about, how they break down, how light they are, and how they can really flex to some extreme curves but still want to spring back to straight. They do keep tents from collapsing, and yet still remaining flexible, in some serious wind.
I would say, look at how your wing collapse in these scenarios you are familiar with, and what could be added where, and at what place where the collapse begins, that would prevent a catastrophic collapse. Would that be the leading edge? I myself don't know. A paragliding expert would know. Would this be the only place you'd need it, for maximum gain? Or would you also need it in the trailing edge? Do you need two of them in the middle connecting both leading and trailing edges (kind of like an H pattern with double cross bars)? How flexible and springy should your tube be, and how to determine a close to optimal tube diameter and thickness? How lightweight do you want them to be, so that it doesn't impact significantly the way your wing flies? What parts do you want to be able to collapse under user control, to do the tricks and maneuvers you guys do by pulling on your strings? Should the stick thin towards those points, or not exist there at all. And so on.
Since these sticks are very springy, flexible, and bendable, I don't think you'd be making a hang glider wing... you'd still be pretty much flying a parachute, like the ones with inflatable edges. But it would be a parachute that has some lightweight structural members that want to keep it in some resting open shape, or spring it back to some shape.
Pull out a fishing rod from your garage and play around with it, as a small scale model that has varying diameters all along its length. Something like a foam "Pool Noodle" is another lightweight flexy example, that wants to spring back to it's original shape, but considerably thicker.
On light sport and homebuilt airplanes, they use thick springy solid fiberglass landing gear sometimes, for it's strength, springiness, and lightweightness.
When I was younger, I was so dead set in my opinions and thought in black and white; my mom once told me, be flexible like a reed in the wind, and you won't break. Like the stem of a grain of wheat swaying two and fro in the wind. Think like that, like a hollow reed... strong, yet flexy. (I didn't heed my mom's advice, but that's beside the point. I still think I'm right, all the time, even when I'm wrong ).
Test my "Choppergirl's Reed" idea; if anyone adopts it and it turns out to save just one life in the future, I'll be tickled. It's not like I invented fiberglass rods... mother nature, really should get the credit.
If the idea on the other hand turns out to not have any merit at all, then toss the idea in the waste bin... no love lost and no egos bruised. Someone with idle time explore it, try it, test it (preferably in a controlled environment/scenario with a dummy pilot load)... and should it work, adopt it. If it works really good and turns out a worthwhile upgrade for all the trouble involved, spread it and preach it, yada yada.
