Anyone growing hardy pecans, hicans, or hickories from Grimo or similar? Looking for seed

Anyone growing hardy pecans, hicans, or hickories from Grimo or similar? I'm looking for seed that has had further chances of crossing. I could of course buy seed directly from Grimo, but I was hoping to find somebody growing their cultivars, (or similar northern adapted Carya) nearer to my location and climate in Denver, giving me a better chance of success.

I can't pay that much for seed, since very few are likely to survive here, but let me know if you are interested and want to work something out.

I have a hardy hi-can (hickory-pecan) from Oikos Tree Crops. It's only a foot tall, long time before it'll have nuts, but I bet you could get seeds from Oikos. They're near Kalamazoo, Michigan. Different type of cold climate than Denver, but still a cold climate.

The owner there has been doing interesting crossing and selecting projects for quite a long time.
