Did generational turnover help create the “Blue Wall” in 1988-2000?

Did older generations tend to be more Republican and younger generations more Democratic in these states, and did older generations dying off and younger generations reaching the age where they start turning out to vote help create the “Blue Wall”?

The issue with this is back then the older generations were the GIs and thus Democratic (see Dukakis's best age cohort being 64+) Indeed, the remaining GIs today are still Democratic (Fun fact: Obama won the 84+ vote).

Might this only be true for certain demographics and regions? For example, GIs were/are more Democratic in the South but more Republican in New England.
