This is a great idea! Maybe for the future, when the full programs are up and running...
It would be nice to have a few committed people continue to live there right now to help with spiritual direction, liturgies, prayer services, whatever!
It seems like most centers are either focused around a faith community as primary or being a retreat center, but it is certainly possible to invite people to take up a simple prayerful life there and or allow for longer term sabbaticals. I think this typ of "alternative" committed secular religous life is a way of the future that may become increasingly popular.
These are a couple of centers in which religious men, women, and secular oblates are living together successfully in community and allowing others to come for limited longer term retreats.
