(OP)
one of the vessel we had the issue of preferential weld erosion corrosion as compared to parent metal (shell course/dished head), up to the height of ~3.5m from bottom dished head. It was repaired by welding.
Advice on suitability of weld overlaying of above specified affected area (say 3.5 to 4m height) by duplex /super duplex stainless steel (e.g. 2707 grade).

Keeping the correct composition and microstructure with no secondary phases is very difficult.
This is why austenitic alloys are most commonly used for overlay.
