Generally I'd advise against changing any of v$ views or public synonyms on them, instead I'd try to find another solution first (like even analyzing DD in 9.2, etc.). One solution to get your own custom v$ views is to make a v$lock view or synonym to your own schema. Local schema objects take preference over public synonyms when referenced in SQL, that way you don't change any of the SYS objects, which is mostly unsupported anyway.
