Artizan are a touch bigger than Bolt Action and Empress. I did a similar project at the beginning of this year and used Foundry, Empress and BAM but didn't mix them between units. Artizan and foundry are comparable, as are BAM and Empress however I wouldn't mix between those two groups. I use mine together but in independent units. I don't have comparison pictures but could get you some this weekend if no-one else can oblige
