In my opinion, design patterns are applied at a much finer level of detail. With other words, your problem is too big to apply a design pattern to.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
I don't see any sort of problem with what you're describing. If you were more specific, or mentioned which parts of this bothered you, then a pattern would be easier to detect.
If you think a section of your system can be used to do something, but is too complex to be used well, you can use a facade to provide a nice usable set of methods to be used.
Say you have a very large amount of classes that need to be accessed to register a student. You can put them behind a facade, and have the facade take care of all the work for you. You just call one method - registerStudent. Sort of a limited example, but you should get the idea.
I don't know if the classes you use to accomplish this are too complex and not subject to change, so I can't say if the facade pattern can be applied.
Don't try to find an excuse to apply some sort of pattern - patterns are solid and standard solutions to problems. Just a thought.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
