In short, no. Not in my opinion anyways. The tiers aren't a measure of anything except the versatility of a class or acf (in the case of things like the Erudite). 29 more spells known radically increases versatility but it's still short of classes who can learn/already know all spells or powers on their lists.
Edit: I think once the list is reasonably accurate consideration should be given for placing Archetypes that radically shift their class' power into tiers.
