That will kinda work but the weakest areas still need to be completely boxed. Ultimately, it will still want to crack from weld to weld, between those areas... The leaf spring area isnt a huge place for cracks unless there is a lot of stress put on it from say, heavy offroading or rot issues. The breaking point is the area between the rear cab mounts and the front bed mounts... that is the transistion point... its inherently weak and the focal point of chassis twisting front to rear....
Here is a picture of a '99-'07 GMT800 frame. The basis design is quite similar to our GMT400 trucks, but you can see a number of ways that GM reinforced the frame structure and near-completely boxed-in the frame transition point, as well as the front framerail section and above the middle of the spring perches. The addition of tubular steel cross-bracing also improved the overall rigidity between the two framrails... whereas our GMT400 has quite a bit of flex because of the stamped flat-stock-steel, cross-bracing.
