Membership site using sub folders

I need a little advice. I’m building a membership site with four or five sections to start. For the last week I’ve been learning about professional membership plug-in, my first attempt was to add it on to another WP network using sub domains.

I finally gave up on that and created a new network site from scratch. Only I used subfolders this time.

My thought was that each section could be a subfolder. That would give me much more flexibility in colors and menus, etc.

For instance, let’s say this site was all about colors.
So there first remains section of the site would be called colors.
There could be a subfolder for red, blue, yellow, purple, orange, whatever.

And when a subscriber logs in, he could be taken to the proper section which would have its own separate identity, look and feel.

So what I want to know is, has it been none before, what are the odds of it working?
