 Yeah, almost got it working with:

 {{{
 div#widgets-right .sidebar-description {
         padding-bottom: 45px;
 }

 div#widgets-right .widgets-holder-wrap:not(.closed) .sidebar-description +
 div,
 div#widgets-right .widgets-holder-wrap:not(.closed) .sidebar-description +
 div.ui-draggable + div.widget-placeholder,
 div#widgets-right .widgets-holder-wrap:not(.closed) .sidebar-description +
 div.ui-sortable-helper + div {
         margin-top: -45px;
 }
 }}}

 However that makes the first widget in each sidebar shift position
 momentarily on drag start, which breaks the drag-helper in UI Sortable and
 makes it quite hard to place the widget properly.

 How about 26168.2.patch: when starting to drag, add "highlighting" of all
 areas where a widget can be dropped, including closed sidebars. This makes
 it even more obvious than a placeholder in empty sidebars.
