Now that would be interesting.
By the way, I sent an idea for a focus for the sustainability workshop (if you still wanted to do that) to your gmail address. The focus would be on ethical symbiosis with the land as a form/system of Elven magic.

Another possibility is a workshop on sensing spirit presences such as the one you describe here, especially in the sense of soul connections with elven folk (be they from the pages of fiction which tapped into another reality, or directly from that other reality itself)
