How do I combine New Blog Template and Batch Create functionalities

The next step of the project I am working on, involves cloning sites.. and that seems to be what “New Blog Templates” is all about

However, I have hundreds of these sites to create.

Batch Create seems to let me create my “hundreds” but not as clones (reading documentation only.. I have not done this yet)

Before I spend a few weeks chasing myself down blind rabbit holes…

Is there an easy way to combine the ablity to create multiple sites and have those sites not be blank WordPress installs, but fuctional templates with data, menus, etc.

I will be going into each site individually to customize, but I would rather make minor adjustments, than recreate entire sites.

Any insight you can provide would be very helpful… just a shove in the right direction…..

Thanks.
