Combined I2C boost converter and dimmer?

Other Parts Discussed in Thread: TPS61196, TLC59108, LMR62421

I am experimenting with using the TLC59108 to control lights for a portable device I'm building, but I'm needing to run the LEDs at higher than the supply voltage (LiPo).  Currently I'm using a separate boost circuit based on the LMR62421. Is TI considering or developing a combination driver with an integrated boost like the TPS61196 but I2C-programmed instead of bit-banged PWM like the TLC59108?
