Not necessarily a bad idea. My guess is you are going to get your fair share of people ribbing you about how you are just trying to get people to send you free beer. Also, if you are going to use HBT as a forum to drum up participation, you might want to consult a moderator to help monitor things. This would definitely help lend credibility to your project.
Other than that, you might consider starting with a "Send me your best clone." type of review. People on here are always trying to clone one thing or another. It would likely generate more interest in the beginning, especially if you are posting the recipes. It would also allow you to compare the homebrew to something people are familiar with. You could also film you and/or your friends doing a side-by-side or triangle tasting.
Just some random thoughts that came into my head when I read this.
