Depending on the program, I might hop across the pond for this. I've been meaning to take a trip to the UK for a while now. I would be more inclined to go to a longer, more aggressively planned conference as opposed to a more casual event. Two months seems short to prepare for this.
On the principle of organising events that I want to attend myself, I would very much like to organise a rationality conference/convention in the UK. I organise events for a living; in addition, in my free time I've organised five ~200 person weekend conventions and several other events.
At the moment I am thinking of a one day event on a weekend or a Friday in August, at Stamford Bridge or somewhere else easy to get to around London. There would probably also be a pre-conference dinner, or private bar night with music.
Costs would be in the region of £50-£100 a head including lunch.
Can I get a show of hands to see if the idea is viable?
