HELP: Is there any way to change default team names?

I just wanna ask if someone knows how to change team names in my career mode...

I am trying to customize my own fictional team using the 76ers team as a base...

I would like to modify the name of the team primarily the text being displayed in scoreboards and the like...

Can it be done using hex editing? What tool should I use? and How can it be done?

Thank you for replying...

May not be possible until Red Modding Center is released, team tab will probably cost you $2. Although it can probably be hex edited, good luck with that tho.
