I think it's allright if you
    1) LockIBase(),
    2) look at IntuitionBase->ActiveScreen,
    3) ReadWhatYouWant,
    4) UnlockIBase()
to prevent intuition to close the screen after 2) and before 3).

I don't remember where but I did id with a sequence like this:
    - GetPrefs()
    - Modify the Intuition pointer image
    - SetPrefs()
Don't know if this works under 2.0...
