Changing the thumbnail view is probably pretty hard, as you'd have to
extend both it's data model as well as the used CellRenderer.

Regarding the rating see also

Working with eog's statusbar is easier than it looks.
The trick is not to use the EogStatusbar members but use the interfaces
of it's parent classes GtkStatusbar and GtkBox to alter it.

The included statusbar-date plugin for example simply injects another
newly created GtkStatusbar inside eog's statusbar using the GtkBox
functions (GtkBox.pack_end).

I'm not that much into Python though, so it could be that there might be
API limitations here preventing that. Although that's hard to think of
as GtkBox is a widely used interface in GNOME.
