I did this in the past, it would probably require reworking 2 things more than anything:

• Relay/GQL implementation
• MUI/Styling and nested components implementation

MUI SSR works for the most part, but I've still found it to be quite buggy. As for relay, the queries would need to be done server-side, and as a result, the app probably would need a bit more load balancing.
