Yeah I guess that could work. Couldn't really be a crew member as you'd need to trigger it at some point when to have the effect. Well of course the crew member could have some trigger for the effect to happen kinda like the rolling blanks fixes stuff but couldn't be all that common and would make more sense to let it be controlled more. I guess it could even be a pearl effect. Other than merging plated cargo, it seems kinda underpowered to me. I mean for example I'd rather take three ones over one three. You'd lose 2 damage dice in the trade and could only live through single 2 damage shot when before you could take two shots of any damage really. So I guess it could even double the value of the combined dice or something like that.
