Multi SCORM Package

First, be sure you test this in the LMS you're going to deliver to. Many LMS products will just break-up a multi-sco package into separate lessons.

Otherwise, can't you setup a table of contents in the packager? I haven't worked with it in a long time now...

If you can, then you can try to have a 'navigate to file' action on the last slide of a lesson, point to the next lesson. However, I don't know if the TOC will allow that.

Additionally, for the LMS to truly support a collection of different scorm files in one package, it has to be SCORM 2004 and support a specific feature (I can't recall it at the moment)...because each SCORM file will 'initiate' the scorm API. So if your LMS doesn't support multi-packages properly, it'll see multiple 'initiates' and throw an error.

So before you get too far in ideal setup, be sure you test a basic package in the LMS first. The mult-sco package may not even be supported the way you envision.
