Yes, and that probably needs to be done step by step, three easy 
candidates for replacing ReadWriteStream with ReadStream are

If I go for class references for ReadWriteStream I find in position 3 and 4

        Smalltalk internalizeChangeLog

which only reads

          SourceFiles at: 2 put: (ReadWriteStream with: aFile 
contentsOfEntireFile).

and

        Smalltalk internalizeSources

the same.

The class DataStream has

     streamedRepresentationOf: anObject

     | file |
     file := (ReadWriteStream on: (ByteArray new: 5000)).
     (self on: file) nextPut: anObject.
     ^file contents

For the rest it is not so straightforward to see what is happening.
