First of all this may be too deep into the system for the Linux Mint Developers and, as we are into Gnome 3, is it relevant?

lots of options
I'm with you. Having a nice default GUI instead of searching for apps or doing some workarounds is a good idea.
I've checked out the "Widget Laboratory", but it's still only a viewer and you have to hard-code (if that's the phrase) the metacity .xml scripts and layout the gtk windows gfx to produce the design.
What I'm talking about is a viewer, that also allows you to "layout" you theme, either with a wizard, or better still a devided window with tabs where you can drop n drop (or load) your graphics and place them in the relivent areas, such as title bar, scrollbar and additionally test out buttons etc.
I use "Gnome Color Chooser" myself, but it only changes some colours of a theme (if the theme lets it) and isn't for changing graphics sadly.
The GNOME Color Chooser seems to do almost everything you want: http://gnomecc.sourceforge.net/features.html
