Editing rosters question

[mtl]

So i posted this question in another thread but i didnt get an answer so ill try making a thread about it.

I have two profiles on my xbox, one that is connected to xbox live, the other is just for offline play (when i turn on my 360 i can sign in on my online account or the offline one). So i want to know if i take the rosters from my offline profile and resign them and stuff so that theyre the NFL ones ( i want to tweak them using finns editor) will i stil get banned from xbox live? my edited rosters wont be able to use online so i shuould be ok right? just need clarification cuz if i still will get banned i wont do this

I have played a game online with just the nfl teams so if you play like that I dont think there will be a problem. I would make my own team and play online that way until yuo find the answer you need. Have a great weekend!
