Architecture duplication and project template services limit

Hello! I noticed there is a limitation of 5 services for the template creation. I need to replicate the architecture of a project for a customer, right now it has 18 services. For now I am creating a new environment on the same project to have a customized mirror of our demo from the production env. Which is not the ideal scenario because eventually we will need to move the customer resources to his own railway account. I thought about creating a script using railway-cli to create a new project and deploy all the services needed. However I am not very familiar with railway-cli yet and I don't know if it is the way to go. Any ideas about different ways I can achieve the duplication goal?
