I also agree with Paully's recommendations. Cost and space savings from common enclosures are usually offset by the arc flash issues. You can expect insurance carriers to start getting nasty about this in the future.
I have seen split enclosures with a dividing wall and a dead front over the 480 VAC side. I'm not sure if this meets all arc flash access limiting requirements, and I'm not convinced it has advantages over two enclosures, but it might be worth looking into.
