You can accomplish what you're looking to do with any bag that has lens dividers. The ideal situation is to have hoods on the lenses, put them in slots front down, especially with hoods, the front element won't contact anything. Use rear caps, or not, it's usually fast enough to twist off the cap as you grab the lens. Work with the bag unzipped or latched, if you have the bag top down most of the time, the rear of the lenses will be fine unless you're working in very dusty conditions. And if that's the situation, you may not want to be chaning lenses anyway.
When things slow down enough, put the rear caps on.
