Using the resulting remapped initial condition, I wanted to see how much this would accelerate the adjustment to a different forcing, so ran another I-case (using the above setup for running cold start but instead from this remapped initial condition). The global means actually look quite good, even at the start of this simulation:

However, looking at just the arctic (60N to 90N), it definitely looks like things are still spinning up after 50 years:
