You can use composer and create theme buttons that use app order and paste them on a layer or 2, then set a button that will switch between the two of them when pressed. The icons won't have any text with them though and could slow transition to the homescreen considerably. Else you could use zen icons and put 12 or so on the home page in same order. If your client wants it, so be it, but I would much rather just press the BB button to get at the appscreen and do something else with the homescreen or do hidden buttons. Hope this helps a bit.
