Power outage during flashing killed my A8 board, would this work as a replacement?

I think the best you could do would be a RAMPS board but they aren't designed to fit onto a Pi so you'd have to run wires between the Pi and RAMPS board. The nice thing, though, is that the Stepstick-style drivers come in a number of varieties, they all offer current limiting, and if you blow one up you can easily replace it.
FYI your stepper motors are referred to as "low inductance" steppers with their 1.65 ohm resistance. They're designed to be able to spin much more quickly than most steppers -- which makes sense I guess because they have that gear reduction attached.
