I'm unable to see the pictures... your server seems to be down.
Such a breakout board is a nice idea.
But I'd include buffers for all signals and fuses for the powers to
protect the Apple 2.
And I'd use a 68-pin cable where I'd put the power lines between the
high freqency signal lines:
16 address, 8 data, 3 strobes, R/W, 4 clocks and 2 interrupt signals
yield 34 pins. the other 34 should be reserved for power. This way
interference between adjacent wires is reduced allowing a longer cable
length.
