Are those surewire boxes available un-configured for more versatile use?

No, there are only three versions. Two are the ones I used - a single
switch controlling up to seven lamps, and four lamps each with their own
switch. The other simply has six in/out connections connected together.

There are other versions listed on the website, and shown in the
leaflet as "available November 2014", but they don't appear to be
available - a five-lamp version of the multiple lamp box, two and six
way versions of the single lamp box, and an eight-way splitter.
