Bigger alternative to Kata sensitivity v

I love my kata sensitivity V. It fit my 13 inches macbook, 50D with 10-22, 55-250, 100 macro, speedlight, etc, even some diapers for my son.
I also bought crumpler 7 million dollar home which I like, but I recently sold it because I just don't like to carry stuff on one shoulder.

Now, I have
17-40L, 70-200 F4L IS, 24-70, 50D gripped, 430EX and some filters

Kata sensitivity fits them all but I have to take the lens out from the body every time.

Can you please suggest a good alternative for my bigger camera gears ?

I am going to asia in a month, this will be some consideration to put some extra stuff on the plane..

Thanks much!

If you want to keep the laptop in the bag, check out the Kata 103 or Lowepro Computrekker AW

Do you think crumpler karachi outpost will be good enough ?
