At this point not many people know how much more rpm the engine can take, or how much boost it can take, but we have a few clues. The relatively low torque and apparent compromise made for increased low rpm driveability suggest aiming for higher rpm torque with the intake headers and cams could yield good results. Seeing how the 3S-GE with TRD cams and various upgrades made more specific torque than the Ferrari 458, despite an older design, things could be promising.

The thing about the TRD motor is that when people say they want 'torque', what they really mean is 'low rpm torque' and giving them that while keeping the higher rpm torque (power) is tough. This is where all the variable geometry intake systems like Toyota's dual runner TVIS (inertial) and multi-length ACIS (acoustic) systems (and exhaust like EXUP on bikes) came in, as well as the assorted variable lift systems. They all are trying to 'double tune' the motors for low and high rpm. And that is probably way beyond what the aftermarket can do because of cost/complexity.
We will only have the cam phasing to play with.
