It's hard to say without doing all the implementation work, but the paper does say that the algo is "...general enough to describe both local polynomial and Gaussian process approximations..." and there is a section called "Local Gaussian process surrogates". So, they do in fact incorporate this in the larger framework of their algo.

In fact, they claim "...that the accuracy is nearly identical for all the cases, but the approximate chains use fewer evaluations of the true model, reducing costs by more than an order of magnitude for quadratic or Gaussian process approximations (Figure 10b)."
