Neither Microsoft nor Sony allow this for security reasons.
Sony is the better of the two, as there are a few games they've begrudgingly given mod support to like this. However the only example I know of off hand is Unreal Tournament and from what I've heard the mod converter is hit or miss at best, and this is for individual maps. FO3 mods can be far more complex and far more resource-intensive so it seems likely they'd have an even smaller success rate with a converter.
Bethesda has mentioned trying to do something more in this regard with Skyrim, and if they succeed hopefully it will follow through with subsequent games as well.
