The difference only becomes more pronounced with spells that have cast times longer than the GCD like Holy, 12 holies in 30 seconds is an insane amount of AoE damage. I feel like the meta for AoE fights would just become PLD/RDM healing while WHM Holy Spams with a BLM to manashift them.

Maybe exageration but yeah this is AST levels of OP.
Nothing would change DPS wise for your example WHM, except Holy. You can get your 12 Stones off right now. I'm not exactly sure how you're thinking this, but recast is not something that is added on top of the cast time. In most cases this would probably make healing worse, as you couldn't interrupt your casts anymore to heal.
