Wget should have a way to filter all href= and/or src= through an
arbitrary command. That would solve in one go two classes of
problems :
- with commands like grep, that of specifying what links are to be
  followed in a more flexible way than -A, -R, -np and friends,
- with commands like awk and sed, that of rewriting links (like
  you are proposing).

The cost would be one fork/exec per page. IMHO quite acceptable in
regard of the very high power/development-time ratio.
