Ah, now I see your problem - callPackage doesn't use the overriden packages.
I've committed a fix (r23613) that does part two of your solution (move
callPackage etc. inside pkgsFun) and adds a function `applyGlobalOverrides'.
For instance, to build Thunderbird 3 with an older Glib, you can say:

  thunderbird3 =
    let
      pkgs = applyGlobalOverrides (pkgsOrig:
        { gtkLibs220 = pkgsOrig.gtkLibs220 //
            { glib = pkgsOrig.gtkLibs218.glib; };
        });
    in
      pkgs.callPackage .../thunderbird/3.x.nix {
        inherit (pkgs.gnome) libIDL;
      };

The first part of your solution is not necessary, I think.
