Good idea, but I'm afraid that doing only this it would still miss:
*very short tones (less than 3 granules long)
*tones rapidly changing of freqs (sweeps)
But yes, doing forward and backward prediction is a good idea.
Well.. there are several alternative methods, check out the method

Let me elaborate just a little on this tonality estimation.
First of all, why do we need tonality estimation? We need it because a
non-tonal sound generates more masking than a tonal one, and thus we need
this estimation to compute the ammount of

Instead of computing tonality, these models perform exponential additions of
individual maskers, so the final effect
