Provided the class_ argument to gettext.translation() accepts an arbitrary
callable the following may work:

current_catalog = gettext.translation(
plugin_name,
localedir=locale_folder,
class_=functools.partial(
MissingTranslationsFallback,
py_plugin=self._py_plugin
),
languages=[current_language]
)
