When forming Jerusalem as any country, especially the Crusaders, one has a culture inherited from that country - such as French or Greek.
It would have been better if there had been a situation and a trigger similar to the formation of Manchu or the creation of a Sino-Altaic culture from Mongolia.
Examples of solutions:
Decision to create Jerusalem - the new primary culture becomes Franco-Levantine, which is in a group with other Levantine (Syrian, Egyptian, Turkish etc) and the existing culture becomes accepted culture.
The decision to create Jerusalem - if the primary culture is Greek - is integrated into the Levantine cultures (this would indirectly help any player at the junction of Europe and Asia having Greek and Turkish provinces)
