OHHhhh...no, I will not change that. If those hallways were straight, the game would be drawing the ENTIRE map from flag room to flag room. This would be a HUGE hit on FPS due to the number of brushes that now exist in the map.
Now I'm no great grappler, but I can move through that hallway without touching the ground in most cases. You of all people should be able to adapt to that part of the map. If anything, I think it adds to the flow of the map, by not being forced through a small corridor. Fraid your stuck with this one mostly for technical reasons. So 2/3 aint bad =]
