fetch all active langs and copy the context re-run your products queries by setting the context language over loop. that should get you what you need.

def get_translated_path(self, cr, uid, path, lang, context=None):
    if lang == request.lang:
        return path

    ctx = context.copy()
    ctx.update({'lang': request.lang})
    view = self.pool.get('ir.ui.view')
    view_ids = view.search(cr, uid, [('active', '!=', False)], context=context)

        if obj.name == path:
            ctx.update({'lang': lang})
            return view.browse(cr, uid, obj.id, context=ctx).name
