NBA 2K14 PC ultimate base roster V33 help

[bullzeyeIG7]

Hey, everyone. I wonder is it possible somehow to add 2 legends to each current roster (UBR V33) .? If you use default 2k14 roster thats possible but after loading V33 it says you may not trade player or release from user made team and thats sad. For example Bird and Russel added to current roster that would be amazing. Anyone can help?
