Yes, there are files you can copy over to the same location on another TSPS.
Under the this path are the "templates" of any packages you created. They are like an inventory of product (with specific version) you then used to deliver an installable package.
The caveat is that you must import on your second TSPS all the base and extended repository images that were used by your "template" packages. Since versions matter in the template that means for example on your 10.7 TSPS if you upgraded from 10.5 and have deployed packages still in use you would need to import the 10.5 repositories along with your 10.7 ones.
