Nice idea, but it appears to suffer the same expansion problem.

As you have written it gives this error:

  Bare %{...} is invalid in condition at: %{reply:Reply-Message} =~ /(.*)/)

Adding the double quotes:

update reply {
  Reply-Message := "foo"
}
if ("%{reply:Reply-Message}" =~ /(.*)/) {
  update reply {
    Reply-Message := "%{1}\\\\nbar"    
  }
}  
if ("%{reply:Reply-Message}" =~ /(.*)/) {
  update reply {
    Reply-Message := "%{1}\\\\nbaz"
  }
}

This gives foo <newline> bar <newline> baz

update reply {
  Reply-Message := "foo"
}
if ("%{reply:Reply-Message}" =~ /(.*)/) {
  update reply {
    Reply-Message := "%{1}\\\\\\\\nbar"
  }
}
if ("%{reply:Reply-Message}" =~ /(.*)/) {
  update reply {
    Reply-Message := "%{1}\\\\\\\\nbaz"
  }
}

This gives foo <newline> bar <backslash> <n> baz
