Have you considered utilising the left side of the UI with a side pop out panel that people can choose to have it stick or hidden, and as you have collapsible command palettes, you have the same for the object palettes, and more space to play with!
IMHO I don't think this would change the simple clean UI of MoI because as a new user you would be presented with the standard layout, and will look and behave as it is now, as the user becomes more proficient and advanced they can start using the object organisational stuff and what ever else would be added in the future, sort of like modules where it doesn't stop a new user from getting started.
