This kind of thing is a matter of how each Services package handles nick registration. Anope uses a grouping scheme, which is similar to the linking scheme that it inherited from IRCServices and the grouping scheme inherited from Epona. I believe Atheme works on a similar concept. I have used other Services packages that do what you want. but Anope is not one of them. We may or may not be making 1.9.x support something along these lines, but for now, it can't do it.
Also, to Martin, a shortcut, you can skip the register part in step 2 of your list and just group to your other nick, it automatically registers the new nick when grouping.
