Correct me if i am wrong here, but from my understanding arsenic trioxide isn't an etchant at all. It's function when used in the warangan mixture to stain a keris is that it turns iron and steel black while not effecting nickelous material in the pamor. That is how it raises the pamor pattern. It is the acid in the lime juice part of the mixture that acts as a gentle etchant.
I don't really know what causes the lines to appear in a twist core Moro kris, but if it is not the inclusion of nickel in the mix i don't think arsenic would be an effective way to raise the appearance of the lines in the twist.
