The latest release of the Move Controller for AI Girl and Honey Select 2 Studio NEO makes it possible to move around and rotate a character's accessories as if they were studio items. Press the new "Accs" button on the workspace panel to toggle this feature.
(A known limitation is that this feature doesn't work for accessories in the extra slots created with the "More Accessories" plugin.)
There's also a small fix to the CharLoader plugin that may improve performance.
UPDATE: Move Controller upgraded to version 1.7.1 with minor bugfixes.
