I've been involved with, and led, a few projects that I felt had little chance of coming to fruition, but they did. The key was to invest time in a well thought out, well defined, and comprehensive goal, and ensuring any actions directly support the goal. That means if you have a solution to an issue that adds weight, no matter how little, it's not a complete solution unless you have something to offset that increase, and hopefully reduce the overall weight. You'll get help if you are serious and treat it that way. Things like aesthetics are squishy and undefined, so you'll need to address those yourself.
