Acutally, I could and I'm not skinny by a long shot.
The purpose of a roof escape hatch is to allow egress when the bus is tipped on it's side. If its flipped on the side the entry door is on, then you would technically be trapped. If one was rear ended before flipping, then that would disable the rear door as well. Studies have shown that in a panic situation, people tend to look "out and ahead" meaning if the bus was on its side, they would now be looking "out and ahead" at the roof hatch which is now in front of them and would pass on trying to remove the windows above them, which are clearly labeled for emergency exit. "out and ahead" is also the reason why aisles are illuminated with low voltage lighting in airplanes, tour buses, movie theaters etc.
At one point in time, there was discussion about having EXIT signs located 1' above the floor in addition to over it, so those that are crawling on the floor can see them. They were eventually discontinued due to design aesthetics and practicality of installation i.e, which side of the door, both sides of the door, reflective tape etc.
That being said, you would need to have a ladder to get through the hatch and practice it's use on a regular basis. Then comes the problem of dropping several feet to the ground, once on top. Unless you anticipate your trailer being flipped on its side during operation (maybe by an angry mob that want's their dog faster).......I would consider another option besides a roof hatch.
