I've had a little more time to digest things and come up with a couple of ideas.
I think my problem with taking the Paladin as a class rather than a Background for a Fighter or Cleric stems from the assumption that a class like the Paladin, Bard, or Ranger has to take up the same number of pages in the book as the 4 Iconic Classes. I had to take a step back and accept that
it is not a given, nor a necessity that each class has the same design flexibility.
The Iconics are Big Tent Classes - they have core examples like Fighter: Slayer or Magic-User: Wizard, but at the same time they are flexible enough to encompass divergence. Fighter: Knight and Magic-User: Sorcerer are completely viable without straying from the tent.
The Paladin, Bard, Ranger, Avenger, Gish-type don't have to be Big Tent Classes themselves just because they live outside the iconic tents. Paladins have a niche between the Cleric and the Fighter. It is a narrow niche and that's OK. It's just one class in this tent, not a ton of variant mechanical paths like the Iconic Classes need to support. Same thing goes for the Bard.
Imagine a Core fighter with a D12 hit die, a cleric with the traditional D8 and the Paladin with a D10. The Paladin has all the Fighter's Armor options, Melee Weapon options, a smaller portion of ranged 1 healing, and his unique detection, smiting, fearlessness, and defensive mechanics. You've got a unique niche class. He won't be as flexible as the Fighter or the Cleric, but he'll still be as effective as a Slayer or a Wizard.
Beyond that, I hope the Paladin doesn't need to match his deity's alignment on the Law-Chaos scale, just the morality scale. Even Neutral Evil and Chaotic Evil deities can see the value in unswerving loyalty among their slaves.

P.S. - I look forward to seeing a Lawful Evil Paladin sworn to the a god of chaos and madness. "Tharizdun demands I beat you to death with this Pork Roast! Surely his wisdom is above the ken of mere mortals."
