These are really good ideas, in theory. My advice would be to find a system that allows you to use advanced "IF" searches as well as advanced "Counter" options. Some systems would be the Rapture system by Iron Realm Entertainment or the father of the Rapture system, owned by Avalonrpg.com. I've heard of a few DIKU systems that have been tankered with grant the advanced options, but to my knowledge, none of them are willing to sell their system for the sake of copyright laws. Good luck with your mission. I look forward to seeing its end results.
