Yeah I could probably handle a grayling. I've never caught one. They look a lot more like a whitefish than a trout though. Visible scales, goofy looking heads, etc. I bet it'd look like a whitefish on the line so even if I have caught one, I might not have known it.

Actually, after looking at some pictures online, I think that a lot of the whitefish I've hooked have been mountain suckers and white suckers. I don't get close enough to any of them to check though.
