Cycling between the brushes in the filtered view could do this (so,
tag both with 'quickdraw' then use the action -- notice their ordering
is not user-controllable in this scenario). I think 'next brush' and
'previous brush' actions that already exist should handle this.

However, they appear not to cycle currently -- ie going back from the
first brush leaves you at the first brush rather than the last, and
vice versa.
 This should really be fixed -- cycling makes more sense for
GimpData's (brush, pattern, palette) than the current, clipping,
behaviour.
Looking at the code in app/actions/actions.c, it seems that all we
need is to change action_select_object() to support wrapping, and then
use that parameter (in context-commands.c and layers-commands.c).

A diff is attached that implements the suggested changes.
