Welcome to the EA Forum :-)
It's admirable that you want to give away the money, good on you!
I also recognise the sense that there's an injustice that holders of wealth happen to have the decision-making power -- I don't know if that's what motivated you with your idea, but your idea resonates with me for that reason.
I'm wondering what goals you have with your approach? Is it about finding the best way to give the money away? Or is it about the impact it will have on those 12-15 people?
You may find it interesting to compare with other things like this which have been done:
- A New York philanthropist decided to do something called flow-through funding -- she gave money to a bunch of people running social change organisations and told them that they could give away the money as they saw fit, as long as the money didn't go to their own org.
- SBF did something similar (not that he's held in very high regard around these parts any more!)
However in these cases, the decision makers were chosen to be people who might be good decision makers. The same applies when people donate to EA Funds. This doesn't appear to be the case with what you're doing?
Interesting stuff! Feel free to DM if you want to have a call about this. I lead the team at Giving What We Can and also oversee the Giving Games project as part of that and have run several Everyday Philanthropist events. My thesis also related to deliberative democracy too 😀
