Want to publish many projects from the same project file with Server 9...Advice?

I need advice. Right now, we're just publishing one project to RH Server 9. We have over 30 functional roles. We wanted to keep all of the topics in one project file, because there are many general topics to be shared. 

In the future, I'm recommending that we publish the 30+ functional roles as separate projects on the server, but all from the same project file. We planned to build 30+ different layouts for each functional role, each with their own Project Name, TOC, Index, window and maybe Conditional Build Expression. (We are currently using FlashHelp Pro. We're not merging anything, but plan to use RoboSource Control. Our tests are publishing the different projects to the same Area on the Server.)

It looks like what we enter in the layout as the Project Name will differentiate the projects and the URLs on the RH Server. So, no problem, right? Will publishing 30+ different projects (from the same project file) tax the system too much? What other complexities or difficulties should I expect? We may grow from 40+ or who knows..I hear there is no limit, but are there practical considerations from having too many TOCs or layouts or projects from the same project file? I'm an Instructional Designer, not a techie. I'd love your advice on this.
