That is subject to review by Google. The first GF OpenMPW was done with options MiM cap (type B), hi-res poly, and deep nwell. The caravel design as currently instantiated has an analog power-on-reset block that uses both a MiM cap and a hi-res poly resistor, so the options can't be removed without redesigning the power-on-reset block, but that's definitely not a guarantee. Sorry I can't give you a more definitive answer than that at present.
