You could use the blue Weller iron (not the red one, it has terrible temperature control and will lift your traces) with the finest tip, or maybe the hot-air rework station to follow @dhylands ’ instructions. The rework station has a camera that can, in theory, provide a magnified view of what you’re doing, there is a lighted magnifying glass over the blue Weller… Being able to see exactly what you are doing is critical if you don’t want to bridge any pins.
One thought … don’t cheap out on the really important parts.
Get a reliable hotend (the ones made by e3d are pretty bulletproof). We spent a long time messing around with hotends that SEEMED like a good deal but never worked properly and caused no end of problems.
