No.

Especially if we're talking about PS3.

However, if you have a PC, there are a few programs that can depackage the game's main files (I believe they are .i3d, correct me if I'm wrong.) And in these files you can find .cfg files, which contain different scripts for the game. They can be opened in notepad, although I don't think they can simply be edited and then played with online.

They had an exploit a while back that if you were host, you could get Care Package nukes and set the nuke to 28 hours on the PC version by editing the CFGs.

Ah, how much fun it'd be if we could modify the CFG's on the PS3.

They PROBABLY have some sort of thing similar to the PC where a lot of the commands are blacklisted(the XP Scaling commands can't be changed) and the nuke exploit was patched.
