Imagine the following situation (see below) where CustomModel1 and CustomModel2 are defined in different modules is there a neat way to order the inherited 'selection_add' states within the  form view statusbar widget ? 

Context :

    class BaseModel(model.Model):

    _name = somename.somename

    state = fields.Selection(

                                selection=[

                                    ('draft', 'draft'),

                                    ('open','Open'),

                                ]

       class CustomModel1(model.Model):

    _inherit = somename.somename

    state = fields.Selection(

                                selection_add=[

                                    ('newstate1','Newstate 1'),

                                ]

       class CustomModel2(model.Model):

    _inherit = somename.somename

    state = fields.Selection(

                                selection_add=[

                                    ('newstate2','Newstate 2'),

                                ]
Ideas : One option would be to create a third custom module that depends on the two initial ones and <xpath> the statusbar altogether. Ideally though there would be some qweb equivalent to the field selection_add attribute to simply add new stages rather than having to redefine the widget.

Thnx for the contributions
