It's the whole looking good on paper thing but it just wouldn't work.
The team members of Bioware would freak if they had to make such an open world game and the staff at Bethesda would have a heart attack if they couldn't use a plank of wood for an NPC. They're just opposite ends of the spectrum and combining them together would create something that Duke Nukem Forever would probably laugh at with glee.
On paper, Bioware stuck to the characters and Bethesda stuck to the world development then sure something might be golden by the end of that but the truth would be that it would be foolish to expect that.
