Wikipedia defines haggis as -
"Haggis is a savoury pudding containing sheep's pluck (heart, liver and lungs); minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and traditionally encased in the animal's stomach and simmered for approximately three hours. Most modern commercial haggis is prepared in a sausage casing rather than an actual stomach."
The biggest problem I see is the oatmeal. That's a definite no-go. The other big problem is that you're on a raw paleo forum, so unless you can manage to get raw haggis somewhere, then you're talking about more of a cooked paleo diet. Of course, not everyone here is 100% raw paleo all the time, so it's up to you to figure out what's best for you.
