You might try something like a bendback, or some of the "flats" type flies typically used for Redfish or Bonefish, with a 2 prong weed guard.
Both styles of flies will have an inverted hook point, which aids in reducing snagging. You can add some stiff material, such as crimped nylon, that is popular with large saltwater or Pike flies, as an underwing on the Bendbacks which will aid in supporting the wing, and act as a snag guard somewhat. Just don't get carried away with the stiff material on such small flies, or they'll be fish proof too.
Here's a couple of Bendback style flies I've tied. The first is tied with yak hair, which is not what you want for such grass. You'll want to use a stiffer material such as bucktail. The hook used is a discontinued Owner brand intended for plastic baits, but works well for Bendback style flies, and gives you a real good idea of how a bendback should look. BTW, this hook is made with this bend in it. There were Bendback hooks made at one time, but most folks bend their own. The older Mustad stainless 34007 was a popular hook for bending, as the stainless was soft enough not to break. Newer hooks, which may have better tempering (harder metal) may break when attempting to bend them. When I tie Bendbacks, I don't even bother bending the hooks now, as this style of fly can still be tied on a straight shank hook & get as good results.
Here's a more typical Bendback, but you can see the similarities.
Here's another possible way to tie these, using an offset plastic worm hook. This hook is a VMC 6319, (available in black nickle & red finish) which has a longer front section than most such hooks so it's ideal for tying flies. The first 2 flies are tied with all synthetics, and a stiffer material could be used within this type of fly to aid in preventing snagging. The primary issue would be hook sizes are not usually available as small as you might want for this type of hook.
This is not a good picture, and the fly is not the best, however it's the best picture I have that shows a 2 prong mono weed guard. This has become my preferred method for adding weed guards to most flies. I use Mason Hard mono for such weed guards, ranging from about 16 lb test up to about 40 lb, depending on the fly size I'm tying.
