I think you two are "talking (writing) past each other". One is a
single distrib. tother several independent. Furthermore, Wiki, claims
that the Chi-square also does tend towards normalcy, but VERY slowly, as
the # of DOF increases.

This is a misconception. There are many distributions that becomeGaussian in the large N limit, but not all.
The chi-squared distribution is an example of one that does not.However, for the SUM of independent, identically distributed random
variables, each with mean mu and variance sigma^2, the central limit
theorem tells us that the distribution (of the sum) tends to a Gaussian
as N approaches infinity.
