Here's a function that I wrote a while ago...almost what you want.
When run interactively, gives something like:

  Replace [n] skip [1] case1 [2] case2 [3] case3?

Press [n] to skip to next match, [1-3] to replace with the
case1-3, [return] to quit.

Could be modified pretty easily to autoincrement
a value in the replace string.
