I'm in this boat right now myself. I'm already decently heavy at 292 pounds, but I fantasize relentlessly about being 400 pounds. What holds me back are health issues and the dreaded "talks" from family members. I feel like I'd finally feel free and happy if I just went for it, but it's definitely a lot to expect others to accept. Perhaps I'll also try this "test gain" and at least bring myself above 300! :-p
