Definitely worth it since you'll have a working backup again, and not at all difficult.
Firstly, I'd strongly suggest you switch the system to single-bios mode if you've not already. It seems to solve all the strange "suddenly my system won't boot" and corrupt BIOS issues; keeping the buggy DualBIOS feature from breaking things when trying to do fancy automatic fail-over and re-flash stuff, by my guess.
From then on you just manually set the active BIOS using the BIOS selection switch. Boot up with your working BIOS, enter Q-Flash, then flip the BIOS selection switch right before executing the flash. I've successfully re-flashed my main and backup multiple times, as well as just using the selection switch to easily move between two versions for testing/comparison. I've also had zero issues with any "soft brick" or boot problems since moving to single-bios mode, when I did experience some before.
