Structuring around the liturgial year

I've been spending a lot of time on the Thoughts from the Sheepfold blog, which is written by the direction of education at an Episcopal church in Ohio that uses the Good Shepherd Catechesis, a religious education model developed by Sofia Cavalletti and a forerunner of the UU Spirit Play in its use of some Montessori methods in a religious school environment.

One thing I envy in the Christian applications of this type of program is the abiding structure of the liturgical year. UU's have traditional services performed at traditional times (Water, Flower, and Bread Communion services, winter holiday service, etc.), but there is something comforting about taking a turn around the wheel of the year within one's community when each station has its own feel, pull, push, and stories. Different branches of UU have it--Christianity, Paganism, Judaism--but what is the wheel of the UU year? This may be something to create.
