Seeking horse breeds with orca - not anymore

One of my horses just got unmade today, for inactivity, though he had a show entry(and placed 2nd!) in July, which the group missed. So, I'm looking for a breed to place him in. I'm not a very active artist, nor the most talented, but if you be fair to me, I'll be fair to you.

I'd prefer to not change his design, since he has a show record and some art under his bridle.

The following breeds are ones I found with Orca mutations:

- advantage, I'm already a member - disadvantage, his ears are wrong
- disadvantage, closed species
- I think? dA's search function found once, but the mutation sheet doesn't list it
- disadvantage, his ears are WAY too short
- advantage, ears are right - disadvantage, he may have too much hair, and I'll need to design a second form... then again, that could be fun.

Does anyone know of any other breeds that have an orca-looking type? He's not that special genetically, a silver black roan sabino(pearl carrier).

So, the group has recanted it's decision, and the horses that were drawn within the last 6 months are still okay, and all horses on the list have till Dec 24 to get drawn. The tags on the journal aren't working, but my Ratsu is safe for now. So anyone who reads this and has a Katala Ratsu, go check the group's journals to ensure your horse isn't on the list.
