This will be very difficult to do from the technical side. The exchange operates on decentralized algorithms. People participate in its work, place their coins in pools, earn interest from exchanges. It will be difficult to stop all this and configure it for a centralized exchange. It's much easier to leave everything as it is.
As soon as I understand, they are going to vote for centralization (or against it). However, even the Uniswap developers have divided into two parts (those, who support centralization and the guys that are against it). Let us simply follow the news about UNI. Unfortunately, we cannot affect the voting result.
