#1 Ok, so let me get this straight....

It is possible, but it requires opening up the case to getting to the
hardware - while the computer is on?

It is possible to swap flash chips while your computer is running, yes.
The term is called hot-swapping, here are some mini-articles to get you started:

#2 Also is it worth it, considering from the risk?

Fact: the board is well beyond its economical life cycle. Opinion: IMO porting this board is not worth the effort.

Those scenarios only happen when you mess up^W^W don't put any thought in handling the hardware.
