I can't imagine there's anything preventing your dogs from eating your
remains. I would worry mostly about the bones. Depending on how they
plan to prepare your remains for consumption, the bones might splinter
causing the dogs to choke. Maybe that's an old wives tale about why you
shouldn't feed dogs most bones (especially chicken).
I should think that the organs and such would be completely fine for the
dogs to eat. My baby girls seems to like meat cooked up with a bit of
garlic, so you might think about having them cook you that way.
