The part I is interesting, and I am waiting for the part II. However, to increase liquidity, I think that key thing should be considered is how to attract crypto enthusiasts to DEXes. By now, they tend to prefer centralized exchanges, rather than DEXes. They have some reasons to think that centralized exchanges can give them better experience, better security, and better supports. Furthermore, fees on DEXes usually high if traders don't own coins of DEXes. such as for dex run on Bitshares network, fees of withdrawals will be cheaper if traders own Bitshares and pay their fees via Bitshares. I meant, building up DEXes more attractive, cheaper fees will help them increase liquidity indirectly for the long run.
