Thoughts on building repositories into composer package to reuse in multiple apps

I am facing a new personal challenge at my work. We had just redesigned a legacy database to a much more normalized, organized schema and we need to port many apps to it. I'd suggested that one way we can do it is by creating a composer package with repositories and models bundled in it and then use the package on every single app. This way we can make changes to the package and update all apps the easy way.

Now, I want to use Eloquent models for such a package, since I found them really nice for building a simple database layer and with the repositories pattern. Problem is I never did this before and I'm kind of clueless about good practices on this.

Are there anyone who has went through something like this? Mind you left any thoughts?
