Ah Gillie! I like your idea of planting little hooks in snaggers with light tippets. How do you play this game? Is it a Slam if you can get one hook in each leg? Do you get more points if you hookup below the surface
Here in Michigan some anglers use tiny trebles with bait for whitefish (unrelated to fly fishing). If you use a size 14 treble, you might be able to get some secondary damage when the treble bites into something else
Honestly, the only time I'd go there is having someone too close who refuses to make space. I don't think I'd change flies, except maybe to add dumbell eyes as already noted above. There's something fitting about dumbell eyes when casting amidst dumbells.
