I love the "Family Album" idea.

I'll also add my voice to the chorus calling for a time slot to spend in celebration of the life of Barry Finn.   I imagine such a gathering would include a big helping of "Tales of Barry." In the fwiw department, if you do schedule a Remembrance, might not be a bad idea to not schedule anything "themed" opposite that time. Maybe an un-themed song circle and an un-themed jam. That would provide alternatives to folks who did not know Barry, or know him well enough to much care about attending something in remembrance of him, while not resulting in some one who has put the time and effort into preparing a workshop in a position that makes it likely the workshop or mini-concert would be poorly attended.
