figured as much cant hurt to ask
and if you want to do both get both
i got oblivion for the pc to fiddle with mods
and oblivion to play for my 360
stil it would be a lot easier ( not too mention cheaper) if it were possibly
yeah if only
The only possibility requires breaking several international laws. You can probably blame those people who thought it funny to install Linex on their Xbox (the first ones) for the more complicated limiters on what you can actually put on your Xbox without having to do anything too illegal.
The Mods themselves are the other side of this. Mods for the 360 (and PS3) are specially formatted to work with those systems. Since the process for converting to this format is something which only Bethsoft has access to, and any attempt to reverse engineer it would likely break a few laws, even if you could install a mod, you couldn't actually use it.
For all I know, the official console mods may have additional requirements as the formatting of data files (bsas) that would prevent even overwrites from working should you be able to apply them.
So in short. No. Not going to ever happen. Just another reason to hate cross platform games. I don't even think hex editors (cheat devices) can be used for the 360 now that I think about it. And they were once a staple of console gaming.
