It's definately an interesting idea. I think this sort of thing needs to be thought about long and hard before any changes are made to the current system though. I have no problems with playing inventory tetris, and I kinda like the idea of rotating items. Something else to think about is item weight. a pair of damaged cargo pants might start ripping if you load up the pockets with cans of beans and then take off at a jog. Though, that thought probably goes in another thread.
