I have done this on two Macs so far, my PowerBook G4 @1.5 GHz and a G5 iMac @2.1 GHz
Both have Application Enhancer as well as Fruit Menu, WindowShade X and other Unsanity products installed.
They still show up in System Preferences, but are not functioning. I'm hoping for updates soon.
However, their presence in my systems had no ill effect on my Leopard upgrades.
