      First, see John's reply.

      But I had a big reply written, and thought I sent it; I have no idea what happened to it.

      Here's the highlights:

      I'd probably try using a recorded macro. For the first set of lines, it would rely on CTRL-A in normal mode. For the second set of lines, nr2char() and char2nr() functions in an expression register in insert mode.

      :help CTRL-A
      :help complex-repeat

      Macros might get a little too complex, and are best for one-shot tasks that you won't need to do very often. So I would also look at :help curly-brace-names to fix the initial idea you had for your function. You will also need to get your setline command right, it should be:

      call setline(".",[line,repl1,repl2,repl3])
