Non-Jews aren't meant to have mezuzot. You are forbidden from gifting one to a non-Jewish friend for this reason.
My question is regarding two scenarios and whether either of these scenarios would make such a gift acceptable.
Scenario 1. - The mezuzah scroll itself is not a traditional scroll. Instead of it containing the traditional lines from Devarim, the scroll is custom. You hire a scribe to write a custom scroll which asks for Hashem to protect and bless the home of this trusted friend of the Jewish people. - In this scenario, the scroll would not function according to the traditional practice and would be a personalized scroll for a specific individual. Not an attempt at keeping a commandment reserved for the Jewish people. You would also be giving work to a scribe and benefiting the local Jewish community in the process.
Scenario 2. - The scroll is non-kosher and inappropriate for Jewish use. Since the scroll itself is imperfect or cannot be used, the non-Jew wouldn't be in possession of a true Jewish religious item. In this context, it would be similar to how you might have a non-Jewish prospective convert keep Shabbat but partially break Shabbat mid-observance as to not violate the restriction of non-Jews keeping shabbat. - Again, this would also be beneficial to the Jewish community since practicing scribes could resell non-kosher scrolls to be used by non-Jews who respect Judaism but don't wish to convert.
How would the Halacha view either of these two scenarios? I know we tend to be restrictive of Jewish articles being used by non-Jews but I have to wonder if we might be able to expand access to non-Jews within specific restrictive terms. Meaning we give non-Jews access to recognize Torah and Judaism and Hashem but we set a separate standard in terms of the items they have access to.
