A Gtk::TreeModel can contain just about any copyable type
via the Gtk::TreeModel::Column<> template. You'd have to try. You can
use the cell_data_func() to set the "inconsistent" property.
I don't personally believe that the Gtk::CellRenderToggle's
"inconsistent" property will be used often enough to justify introducing
a new 3-value type and a Gtk::TreeView::append_column() convenience
method that uses it.
I find that this part of your answer belongs more to the discussion around
topics like "Mapping of model attributes with unknown values to a corresponding
widget display", doesn't it? ;-)
Different issue:
How do you think about improvements for the grouping of row/column headers?

Markus
