I am not quite sure what you mean.  It sounds to me that you are putting forth an argument of the form:

Given condition A, quantity Q takes a maximum when condition B holds.

Thus, for any condition A' that is similar (semantically?) to A, we have that, given condition A', quantity Q again takes a maximum when condition B holds.

(here, we have specifically

A="sum of numbers is fixed"
A'="sum of digits is fixed"
Q="product of numbers"
B="numbers are all equal"

)

If that is your argument, it certainly falls short of a verification.  It is at best solid intuition.
