Well, that it's all up to you. If you feel that the name/player means something to you, then why not? Alex Zidane Jr, II or Zidane Alex could work. I will replace my 23yr old Vidić to a 18yr old (8*) Vidić next season (or later on, depends how he will perform next season).... The same will go with Olić and Salihamidžić, its kind of players that I respect, both as football players and personalities. I "re-namned" my 19yr old youngster Schneider to Džeko, and my 23yr old Džeko to Mandžukić and it worked fine...
If you manage to get/grab a couple of youngsters next season, go for it. You will not regret it. Just look at my team, will have Džeko,Jovetić,Lulić,Begović,Cana and Vranješ for another 5 or 6 season in good shape before they start to "decline" and could be replaced. It's like Miku,Michu,Papaelo etc for you. This is the kind of players you have a special boundary to. ...
