I have seen this sort of thing done before. For example, in the JODA Time library, ReadableWritableInstant (mutable) extends ReadableInstant (immutable). :-) However, I agree with you in this case. Using the word "unmodifiable" implies that subclasses will be immutable, whereas "readable" only suggests that subclasses will be able to read its value.
