Are you sure about four digits? You would need at least 13 bits A2D.
PCB layouts beyond 12 bits are tricky. You need a very good noise
controlled PCB for it.

Hi Linnix,

At the moment I would settle for what ever I can achieve.
Four digits would be great. Three would be fine. Two.... Well I can do
better!

I'll gratefully accept any help I can get.

If you don't have any size requirements, we can probably build you a
double LCD board. (using 2 LCDs x 12 segments x 4 commons).

The following is challenging because of the tight spaces (AVR
controller at the back):
