Why should "flashing of uboot-environment" fail? If you configure for
redundant environment, you should always at least have the previous
copy of the settings).
As for the rest, kernel and file system, these are application data
from U-Boot's point of view, and you can use any method to update
these - alternate copies stored in flash and toggled with environment
variables, automatic update from USB mass storage devices, automatic
updates from TFTP server etc. - Have a look at the manual for details.

Why inventing another (square?) wheel when there are already several
other options available?
