I've been thinking about this as well. The 4x20 info display I did got me thinking that I really needed a more versatile display, so I've been tinkering with some small TFT displays that I had laying around. I would think that a TFT (even with touch) display and an ESP32 would be a good start, and with a decent core to decode and display Signal K, it would make a good portable display. You can buy ESP32s and ESP8266 units with a battery backpack - then wire it out to an SPI display?
The other one is some of the low cost ePaper displays that are becoming available.
Enclosures is ALWAYS a problem. 3D printing might be the answer, but I don't have any experience with that.
I think it's important to keep it simple. Waterproof POE if you need power, wireless if not. For POE, you would need home runs back to a central switch, but it is relatively easy to implement and very common.
