I don't see any benefit in processing changes at the AST level. The
same results can be achieved by comparing the source of two methods,
perhaps pre-compiling them and comparing their ASTs if you want. Plus,
by having the method source, the VC system is more robust.

I was hoping you were going to ask a more general question, such as
"is this list of features sufficient for a VC system?".
