Sounds great! The thing that I find myself twiddling with the most are my choices to try to have as few points left over as possible. If you can make it do "spend points efficiently and have as near zero design points left over as possible" that would rock!
Off the top of my head, I'd say it'd need some kind of prioritizing system so you can select specifics (ex: I want
this castle no matter what, has to have +4 fire magic, don't care too much about starting dominion, etc... ) I have no clue as to what you could do or not, so these are just suggestions.
I think it's great that you're willing to give your time to the community. Finding a niche and filling it is a great way to contribute to a game you enjoy. We all owe a debt of gratitude to the people that freely contribute their time, effort, knowledge, and resources to make this community what it is.
