The statement in the original post is true. This follows from a [recent result of Pintz][1], which is a common generalization of the Green-Tao theorem and the Maynard-Tao theorem:

**Theorem.** Let $m\geq 2$ be an integer. Then for any sufficiently large admissible set $\mathcal{H}$, there exist $h_1,\dots,h_m\in\mathcal{H}$ such that the set
$$\{n\in\mathbb{N}:\ \text{$n+h_1,\dots,n+h_m$ are consecutive primes}\}$$
contains arbitrary long arithmetic progressions.

Indeed, the special case $m=2$ is already sufficient to derive the statement in the original post.
