Will a Billingham Hadley Pro fit an ipad behind divider?

Thinking of picking up a billingham hadley pro. I want to know if anyone has tried to fit a ipad behind the divider.

I plan to mainly use it as a lens bag while shooting. So - 1d mk iii + lens in hand (prob my 50 f/1.2

70-200mm, 580 ex II + 2 sb-28/triggers in the bag

but for travel I'd like to be able to fit the 1d III (no lens) + 50 f/1.2 + the ipad without to many problems.

Insights would be helpful

It can fit my 12" laptop, so I guess an ipad won't be a problem.

but I think you'll be better off with a hadley large since you'll be packing a 70-200.

I have a Hadley Pro on order and I don't think a pro body with a lens attached will fit. The interior dimensions are 12.5 x 3.75 x 8.75". My 5D is close to 4" as it is.
