I would say that already with a screen like the ILI9488 3.5 inch (480x320 Pixel) the refresh rate is almost at the limit with an ESP32 wroom 30 Pin.
If I were you I would limit myself to making an STL containing ESP32 and screen, or a PCB with the connection traces between ESP32 and the screen.
Combining 2 ESP32 together seems to me a more complicated thing (and perhaps with the wifi connection you save some connection)
Here you can see a project I made for a table clock with wind signal (code included).
