Currently this isnt possible. AFAIK this isnt trivial to add - though to be sure of this I would need to attempt to add it and see what problems come up.
When a region is initialized drop-boxes are defines but this happens in C so we would need to add a way for the C code to call out to python functions that define their own drop areas (which may change - added on not each time). Another way could be to have these drop boxes defines as persistant data that python can go in and manipulate - but this isnt in keeping with our existing design... so will ignore this for now. Callbacks to define a drop area could be done like region draw callbacks in source/blender/python/intern/bpy_rna_callback.c So you could do something like... def box(self, space): return x, y, w, h handle = bpy.types.SpaceView3D.callback_add(drop_callback, (self, space), 'DROP_RECT') This would be different to existing use of callback_add since it applies to a space type - not the instance of a space type. Existing use of callback_add looks like this... handle = context.region.callback_add(draw_callback_px, (self, context), 'POST_PIXEL') --- 2 Other ways to do this *(which I think are bad options...) * using bpy.app.handlers style callbacks --- this fits poorly with the design of this api which is meant for python to handle events in the application (render, load, save, quit etc) * being able to register a subclass of a space type that defines a calls to define drop areas --- overkill.
