I don't think that would have much of an impact. The focus on profits from VCs/investors isn't due to the corporate structure of the company, but the VC Firm's internal metrics -- the 10-year fund lifecycle, LP demands, etc. Also the mechanism of leverage isn't the fiduciary duty that's placed on LLC / C-Corp management -- the idea that businesses are legally bound to chase profits is misguided. Company management must act in the best interest of shareholders, but have an incredible amount of leeway when doing so. The leverage from VCs comes from their ownership of significant chunks of the company and board representation. They can replace the management team if they don't acquiesce to VC demands. Changing the corporate mission statement won't mitigate these problems.
