Existence of RCD(2,3) metrics on spherical space forms producing Ricci-limit cones

Determine whether, for each discrete group Γ < O(4) acting freely on S^3, there exists an RCD(2,3) metric on the spherical space form S^3/Γ such that the metric cone C(S^3/Γ) is realized as a noncollapsed Ricci limit space.

Background

This question probes the smoothability and realizability of metric cones over spherical space forms within the class of noncollapsed Ricci limit spaces. While certain ALE spaces and cones (e.g., over the Poincaré homology sphere) arise from Ricci-flat metrics, a general existence result for arbitrary free Γ-actions on S^3 is unknown.

An affirmative answer would tie together RCD regularity, orbifold metrics, and the structure of cones appearing as limits of smooth manifolds with Ricci curvature bounds.
