Not within in Zope 3 at least...

As I said on IRC, enhancing ITranslationDomain would change the contract
of this interface. Third party implementations of ITranslationDomain
would no longer comply with the old contract.

It'd therefore be better to come up with a new interface that combines
ITranslationDomain and ILanguageAvailability.
zope.i18n.translationdomain.TranslationDomain could then easily
implement this interface and also be registered for this interface...
