This sounds a great idea, I would just like to add that when it comes to the specific case of the Welch, one of these might be worth consideration:
Aoki, S. (2020). Effect sizes of the differences between means without assuming variance equality and between a mean and a constant. Heliyon, 6(1), e03306. https://doi.org/10.1016/j.heliyon.2020.e03306 Delacre, M., Lakens, D., Ley, C., Liu, L., & Leys, C. (2021). Why Hedges’ g*s based on the non-pooled standard deviation should be reported with Welch’s t-test. OSF. https://doi.org/10.31234/osf.io/tu6mp
