Sure - you can put a net on. Several smaller nets or screens would be easier than one large one. It can be a bit confusing/frustrating if you tackle trying to hang too large a screenful at once.
At this point in flowering the plants don't grow much in length, and you can't expect to be able to just bend and mangle them all into a screen and have them bounce back and fill the are with new growth. But you can tie things down to get the canopy fairly flat, and make them much happier.
Your plants do look a bit light deprived. They'll grow much better when they're not crowding each other out so much. Once you have a flatter canopy you can lower the lights to the optimum distance.
Of course they can still bud well and grow big buds. They're healthy plants and you haven't overfed them which is always nice.
Accept that you'll have to remove a lot of growth at some point. Its safe to say that you have more plant matter in there than will grow well with the amount of lighting you have. Feel free to chop some out and remove shaded areas. Give yourself and the plants some breathing room.
