Why do you want to buy Publisher, if you have FP?
If your host allow you to have subwebs/subsites and the ability to set unique permissions, then yes
you can use FP to set permission on a subweb, where all content within the subweb is restricted to
subscribers, however you would have provide the login info to each subscriber.
A better approach where you can control access to individual pages and allow users to sign up and
manage they subscriber profiles, etc. is to use a server-side script, such as ASP, ASP.Net, PHP etc.
depending on what is supported by your web host and your knowledge or willingness to learn to code
in the supported language, as in most case this would need to be a custom solution, especially if
you will be charging for subscriptions, etc.
Here is a example of a subscription based site:
