I just caved in and ordered the maximus-3 hooks and the blue-ox adapters. Now I'm in and I'll have to figure these things out too
From this thread on Wrangler Forum there's a picture of this setup and they used d-rings on the HR's tow hooks to attache the cables:

This could be a pretty straightforward option for the safety cables. There is still the question of the electrical wiring, the break-away cable, and the air connection (for DPs).
