Your cranks will most likely sit further outward from the frame with the new bottom bracket so that much effect your chainline negatively depending on what kind of drivetrain you’re running

The spindle is longer, so the cranks will be slightly farther apart. You might not notice. It may affect front derailleur, but might still work. Worth a try.

Must be same threading.
Must be same shell width (mostly)
You can mess around with the spindle width, but you might end up pedaling like a duck, or your cranks/chainrings might hit the frame. I think you are probably close enough.
If it all fits, don’t forget to check the crank bolts after a couple days of riding.

Usually the fear is that it’s too narrow, so the inner chain ring might hit the chain stay.
Try it if it’s not too big a difference.

Doesn’t have to be exact but it does have to be the right size

As long as the axles are the same length you are fine
