Have you considered using a ClassBox, available from SqueakSource.

Let's change one of the tires while on at full speed: create a new  
ClassBox which includes all of your car. In that isolated box change the  
tire. If this works out fine, release the changes to the running car's  
ClassBox. A more practical Smalltalk example is to change the compiler in  
the running system, this needs the compiler.
