2011 RX-8 R3 here! Who's the third? :]
If my research is any indication, you'd likely be happy with the Porterfield R4-1 or Carbotech XP8.
I'd likely be running the Carbotech XP8 myself if I didn't have Racing Brake rotors with their weird pad compatibility issues.
Barring Carbotech (sadly), the Porterfield R4-1 is probably the pad I should have bought in retrospect. Lots of bite and a massive operating temp range. The only penalties are a slight excess of noise, dust, and wear at low temps.
Instead, I chickened out and got the Porterfield R4-S. It's fine, but I don't know how much better it is than stock at high temps; it's supposed to be, but I haven't explored the limits enough to say for myself.
As for Hawk, their only pad that looks decent is the HPS 5.0, and there are better options. Everything else generates way too much noise and/or dust and/or rotor wear for its performance level. I find it hard to see the point of that entire brand, honestly. Their pads would likely eliminate your pad transfer problem, just because they're so abrasive. But that's kind of a silly price to pay IMO.
