Something that might have a better chance of yielding superior results is to use 1-ply or even 2-ply for the variance reduction computation instead of 0-ply, at least for the first or second steps of a rollout trial.
This is already the case. Variance reduction for n-ply rollouts (n >= 1) is done at (n-1)-ply.
Obviously this would slow things down
This is not an issue. The costs of one more ply and variance reduction in number of evaluations are similar (x 21). The worst case would then be a slowdown of 100% instead of 5% or less, but the same evaluations are used for both features so the slowdown is very small in practice, as long as the variance reduction ply is less than that of the main evaluation.
