Nah, paladins only really care about Str and Con, and it's not like spellcasters are locked out of higher level spells anymore if they aren't 18+ in a score. Go Str and balance Con and Wisdom and you're good.

If the DMs an old person you can even ask them to use Wisdom for the Paladin spells if you take Oath of the Ancients and spin it like that, 3.0 edition and older dms will probably agree out of pure nostalgia.

Alternatively, flex build for someone using roll for stats that got good rolls.
