I finally found how to do it.
You get his cyberface, portrait, commentry name, and in menu name by doing this! should also work on a association:
I will make rubio replace sun yue, for example:
1)to get the cyberface, by Kris:
"First find the iff number of sun yue which is png1566(make a backup for it)
then change that number to rubios png number like png1601
Sun Yye png1566 -> png1601"
2) to get the ratings and the tendacies etc, search in REDitor for ricky rubio
then just copy all his stats to sun yue, via this program, another roster editor or the ingame editor.
3) for the commentary name, menu name, portrait :
download reditor V0.4:

in it, search for sun yue, then edit this stats:
LNAMEID-2166
FNAMEID-175
PORT/CF ID 1601
now you have rubio instead of sun yue in game.
you could put him on any team just like any other player, and he should also be on your association.
my problem is this:
i already have my assoc started, and i dunno how can i edit my assoc roster....
possibilities:
-)to convert the assoc roster to a regular one, do the above and convert back to my assoc roster
-)to import a player from the roster to my assoc
-)to somehow edit assoc files with reditor, as i did last year with flynnroster editor (is that feature planned?)
hope you enjoy this,
also, hope you make me enjoy this /=
