Best way to create "import" only project for use by other web-apps

Like the title says, I’m on a mission to try and build out an import-only Yii2 project for use within other Yii2 projects.

Use Case: I have various separate applications that use the same models – all of which are built on ActiveRecord or the like.

This would allow me to generate models via Gii (or similar) once and have it cascade out to the other applications on-demand. I have read through the docs and found this: http://www.yiiframework.com/doc-2.0/guide-tutorial-yii-integration.html#using-yii-in-others but not sure it’s completely relevant because that’s using items such as helpers or the application itself.

Am I overcomplicating it? Anyone else have any success stories or tips for the best approach? Thanks!
