Well, good luck to you. i wouldn't do that to a crab cake, but I'm a bit fanatical about them. I also wouldn't put diced red and green peppers in a crab cake, but again, that's just me.
If I can make a suggestion, an oily fish like salmon, mackerel or bluefish, if you can find it, makes a GREAT "crab cake" that stands up to the smoke flavor. You just smoke the fish first, flake it and use it in place of crab meat in your recipe. The sweet, delicate flavor of crab meat (I'm referring to Atlantic Blue crab meat) really doesn't go well with smoke. It actually turns out kinda bitter, whereas, the oily fish really takes to it well.
