I'd suggest that when on an approach, the callout should reference the minimums. The only real benefit of a callout is when your IMC and can't see the ground. When IMC, the only real altitude reference is against the minimums. AGL doesn't really provide useful information. As said before, there are plenty of locations where the 500 foot callout is below minimums, such all approaches to my home field (IYK) - the lowest AGL minimum on an approach into my home field is 703 feet.
