Test on Difference in Mean Correlations

Hello:

Is there a way to perform a formal statistical test on whether two
mean correlations [calculated from data from the same sample] are
significantly different from each other:

H0: mean[corr(1,2), (corr 3,4)] = mean[corr(5,6), (corr 7,8)]

I realize that since correlations are not additive, in order to
calculate the mean correlations one would likely use the Fisher's z
transformation or perhaps use squared correlations, but I'm stuck
after this point.

I realize this is a peculiar question--just curious if hypothetically
this would be possible, and if so, how to do it.

Thanks!
