I have some experience of chassis repair, building, and extensive modification, none of which was done on Sevens. I would cut out the bad section and find someone who can bend up a new section of ordinary mild steel, to the correct profile, before welding it in. On C section chassis in the past I have welded diamond shaped plated to the vertical faces over the welded joints, or made up another C section that fits inside, this was welded all the way round, and had several 3/4" holes drilled in it, to enable a series of large plug welds.
So I think your idea of replacing the rot & welding in a box as a strengthener sounds like the right way to go. Tacking in the box before you cut out the bad section would have the added benefit of everything aligned while you weld in the new bit.
