Tone & TLC5940

Not sure I want to switch to shift registers.
If I was able to change the core, what would I change here?

#if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__)

#define AVAILABLE_TONE_PINS 1
#define USE_TIMER2

const uint8_t PROGMEM tone_pin_to_timer_PGM[] = { 2 /*, 3, 4, 5, 1, 0 */ };
static uint8_t tone_pins[AVAILABLE_TONE_PINS] = { 255 /*, 255, 255, 255, 255, 255 */ };

#elif defined(__AVR_ATmega8__)

#define AVAILABLE_TONE_PINS 1
#define USE_TIMER2

const uint8_t PROGMEM tone_pin_to_timer_PGM[] = { 2 /*, 1 */ };
static uint8_t tone_pins[AVAILABLE_TONE_PINS] = { 255 /*, 255 */ };

#elif defined(__AVR_ATmega32U4__)
 
#define AVAILABLE_TONE_PINS 1
#define USE_TIMER3
 
const uint8_t PROGMEM tone_pin_to_timer_PGM[] = { 3 /*, 1 */ };
static uint8_t tone_pins[AVAILABLE_TONE_PINS] = { 255 /*, 255 */ };
 
#else

#define AVAILABLE_TONE_PINS 1
#define USE_TIMER2

// Leave timer 0 to last.
const uint8_t PROGMEM tone_pin_to_timer_PGM[] = { 2 /*, 1, 0 */ };
static uint8_t tone_pins[AVAILABLE_TONE_PINS] = { 255 /*, 255, 255 */ };

#endif

As another alternative, could I change the TLC5940 library to use a different timer?
