Do it! You will be limited by vCore on those boards anyway and I believe that it may struggle to push the BCLK too as you're obviously straining four processors rather than just the one.
If the BIOS recovery procedure works with a USB device, then I'll jump right in. Still to check that bit out. Other than that its about 2 weeks lead time on a new one and working 12h/7d for a month to pay for it.
