My guess and the way I took it was that he was wondering if there would be any benefit to weld some sort of diagonal braces of some sort INSIDE the tube as he builds it.If this is the case its an interesting one.Has me wondering why we wouldn't see more of them with an open concept like a crane boom.Most likely that would be too weak.
I would suggest using the heaviest possible material from the git go.

Lattice metal type boom??? I think it would be totally impractical. Has anyone seen a lattice built backhoe. You would have to be an engineer to develop the right spacing and angles for this type project, plus all the welding for all the little pieces, with the correct angle , cut to fit.
But, I guess it would be a fun project if you had time on your hands, and the equipment to cut and grind the angles and weld a couple hundred pieces of metal to form the boom design of your choice.
Irving makes the bottom line point. The bridge/boom should have added section as far as possible from the shear center of the beam axis. That's why here is an "I" in I-beams. From a practical standpoint, a thickwall tube would be my suggestion for a boom candidate. Then add the gussets and shear walls.
If you are going to dig soft ground, pull up small trees for replanting, or bury a water line, you may not need too much added metal. Rocks, clay and concrete busting are another matter.
That's the engineer's opinion....
