Red Cedar stump -- berry seedling nursery?

Hi
I've got a 15 year-old western red cedar stump that seems to now be decomposed enough that I think it might serve as a good nursery for some red huckleberry (which grows out of western red cedar in the wild). I'd like to get my hands on some red huckleberry seeds to try to get them to root into this stump. The stump is about 2.5 feet across and 3 feet tall, located on a slight incline and gets a fair amount of sun. Zone 8b. I've thought about a hugel mound but it isn't in a location where I want a huge mound (aesthetics).
1. Does this seem feasible?
2. Any other ideas on other edible berries or plants that might take well to this old stump?
3. Any ideas on where to get red huckleberry (Portland, OR area)?
Thanks!

In our area there are a few things that can be found on a decomposing cedar stump:
- Salal
- Bunchberry/dogwood
- Red huckleberry
- Salmonberry
- Western Hemlock seedling
