There are 3 external address bits on the I2C controller boards and the displays are cheap, so why not have at least eight displays, instead of 5 or 24.

24, of course :-) You can multiplex I2C to three segments.

let me start with 8 first, I can easily clone this twice later on, If I need to ;)

That sounds like a plan, I'm curious how it turns out.
