I am the mysterious professor.
Just because a rule says it can happen, doesn't mean it should. Paladins didn't exist on Krynn. Wizards of High Sorcery wouldn't allow a Kender in any of the orders or towers.RAW there is no prohibition on either Paladin or Kender blackrobes.
If you do this you're raping my childhood. The lore of the setting should supersede any rule.
