Kiwis are tart a bit, and with 4 limes, I think this is pretty tart. Coconut water vinegar is good why not use all of that instead of ACV also? I don't add water to sauces. That's all the comments I have. Sounds like it could be good.
One more thing. Change the molasses to honey. Molasses is for BBQ, to me. Honey works great with limes and fruit.
