Software Deployment

So here's the situation. I'm trying to figure out the best way to manage and Office 2007 deployment. This is the first chance I've had to dig into this. I've read a good deal of the information out there and I'm not seeing a good way to do this.

Consider this. I have users that need varying combinations of the following:
Word, Excel, powerpoint, access, outlook, one note, publisher, groove

I've read that you can use a second MSP to modify an existing installation that was deployed with a first MSP. Not a good option because the MSP's are timestamped, and you can't apply MSP's than are older than what's currently installed. So if I have Word and excell, and I want to add publisher I can. However if I later want to add Access (whose MSP was created before Publisher) I can't.

I've read that you can use the /modify command, and create a new config.xml. That would work for adding components, however how do you control sub features, such as the handwriting fonts for Onenote? If this installs all subfeatures of Onenote, then I'd be ok with hit, but it appears only to use the defaults.

Any thoughts here? Is there some way to do this that I'm not seeing, short of creating MSP's for every possible combination of Office 2007 features?
