I don't see how this would be possible.
Todd Howard should have never opened his trap about that. It's just not gonna happen when you consider that Bethesda would have to take a bunch of mods, ensure compatibility, waste countless man hours on quality assurance, then send it to MS to do the same for the Xbox.
Or they could just have their guys in house churn out some DLC from scratch and peddle it to console users without the hassle.
Not a tough decision.
