I think you could take the approach of using log-linear modeling to statistically compare the two matrices to one another, rather than treating diagonals and off-diagonals as something different. With this approach, you could also collapse the matrices by phonetic features (voicing, place and manner) before comparing, so as to determine if changes were limited to a particular feature. This might be relevant: Bell, T.S., Dirks, D.D., Levitt, H., & Dubno, J.R. . Log-linear modeling of consonant confusion data. Journal of the Acoustical Society of America, 79(2), 518-525.
