I don’t think this is necessary. UNI holders forgoing fees is more than enough incentive to provide liquidity on Uniswap over its competitors, not to mention the technical advantages protected by the creative licensing scheme.
Additionally, pair selection is implicitly political and opens up an opportunity for our competitors to service the “rejects.” Not to mention adding this other DAO and compensation opens up another political attack surface that could be compromised. I like Uniswap as completely neutral exchange infrastructure.
