Should work the same aerodynamically in a pointy, but you guys have fixed stations for weight. Move CG aft of the center of lift and horizontal stabilizers/elevators no longer have sufficient authority to maintain stable flight. Often CG is calculated within inches-feet so pushing back a part of the load a few feet can be catastrophic. Let's say you have a single large item in the back that comes loose. Aircraft pitches up during rotation and that item slides back. At worst, the result could be continued overrotation followed by an unrecoverable stall.
