I would likely be comfortable physically replacing the board; I assume it wouldn't be much different than replacing a card or board in a PC. But I wouldn't be confident that simply replacing the board will allow the unit to boot up normally and allow me to upgrade the firmware.

Some confirmation of the "big picture" would be helpful; the order of doing things, etc.
