I like the concept but please correct me if I'm mistaken that this is essentially a Kickstarter approach of validating a product concept but backers are putting in more skin in the game than the one who came up with the idea? I think it's important to validate an idea and people's willingness to pay but that is based on trust/brand/distribution/credibility as well. Instead of a pay option, it might be more interesting to harvest emails for early access or updates.
