I'd be for this approach. Later you may want to have option  
containers and the options
set explicitely override the corresponding ones in the container.
You can further evolve the container into a full-blown cascading  
stylesheet management.
[this maybe what property tree is for, I haven't looked into it yet]

By choosing this route you can progress incrementally and add  
functionality as you go
(either as part of the SoC project or later).
