If your goal is to estimate the magnitude of the difference between groups, then your procedure is fine (in principle). You can decide whether it's more meaningful to consider $\mu_1-\mu_2$ or $\mu_1/\mu_2$ based on whether the original scale or the log() scale is more sensible to deal with. The HDI's won't be exactly the same (because HDI's aren't invariant ...
