I want to go to one of those fly fishing only streams and start tossing poppers like you would use for bass and panfish. Everything would be according to the letter of the law, but it would still make the purists wet their waders to see someone tossing some honking big frog with rubber legs instead of a size 22 midge pattern. I would probably catch some nice trout, too, because a big trout wouldn't want to pass up a big meal, especially something he's never seen before. That would make the purists do more than just wet their waders.
Trout are pretty smart critters for fish. He would rise up to check out the popper and then go about his business.
