Keep in mind the REASON grain is smoked -- it's because drying malt requires heat, and a couple hundred years ago (and beyond) they had no way to separate the smoke from the malt like they do now. So there's a tradition of it (specifically, every beer on earth was smoked). Oh, and it works.
Doesn't strike me that getting your hops all wet then smoking them, then drying them in the oven, would be good for the hops. And you'd need to use a lot of hops to impart enough smoke flavor. (Note - if you try smoking the hops without wetting them first, you're wasting your time.)
I also wouldn't be surprised if you got some real harsh flavors from the smoking process due to the chemical reactions occurring during smoking.
And besides, what could you possibly gain from this? If it tasted any better than smoking the grain, breweries would do it.
I'd rate this Very Low Probability of Success. But heck, go for it!
