Please help me with Euroleague expansion (PS4)

[kabamaru]

Hi guys,

I just want to use the default NBA roster and add 6 expansion teams from Euroleague to play in my League

Real Madrid
CSKA Moskow
Barcelona
Fener
Panathinaikos
Olympiakos

There are guys who have done a tremendous team creating logos and players etc but they have done it in the position of the NORMAL players.

Is there any way to combine two different rosters etc?

Easiest way would be to replace some of the historic teams and add them as an expansion, but how could I do it without creating all the 6 Euroleague players from scratch?
