This sounds like a really bad idea. With orange juice it takes less than 30 seconds to differentiate the versions. If this was done with something like Microsoft Word you would probably have to spend the better part of a day teasing out exactly which features you needed or wanted. I think a semi relevant modern example would be how the release of hitman 3 worked out. They had to make a flow chart of how to buy the right copy of the game with the features you wanted.
