Yep, good data (especially on the function of the PMIC) would be pretty nice, at least to get a rough idea of feasibility.

Oh yeah, it's mentioned that the hashrate is proportional to the core voltage. I'm guessing that's got an internal voltage-controlled PLL scaler? It'd be good to know the formula for that, or put some Vcore data on your first-post W/GH chart that could be extrapolated. It'd be a good reference to get people thinking.
