All-pass gain maximizer

Given that
1) humans are relatively tolerant to phase distortion
2) For a given magnitude/perceptual output, there exists many different transfer functions
3) some of those transfer functions may have other peak levels

Would it not be possible, given some perceptual model and sufficient look-ahead time to insert an allpass-filter with the purpose of reducing peaks?

'Phase rotation' is used for processing voices in radio. It reduces the asymmetry of the wave form and therefore allows a louder signal with the same peak level.
