I count 6 ADCs channels required.
I suspect the only single-chip soloution would be a microcontroller of some sort.
yeahhh i have circuits already done for the ATSAM4SB which is a very nice choice, and only around $2.50 or thereabouts in appx 10k volume.
2 Microcontroller SoM board in KiCAD GPL'd http://www.gplsquared.com/SoM1/SoM1.html
Make the IO controller swappable.
Board done up for LPC176x 100 pin chips, but easy enough to modify for any kind of similar chip and also go about standardising the connections.
Another option is the ST chip http://www.aliexpress.com/item/STM32F103ZET6-STM32F103ZET-STM32F103ZE-STM32F... (which is supported by the 'free' coocox compiler http://www.coocox.org)
Has LCD controller. Requires RAM: http://www.aliexpress.com/item/10PCS-IS62WV51216BLL-55TLI-IS62WV51216BLL-55-...
And plenty of NAND to store graphics http://www.aliexpress.com/item/FLASH-WINBOND-W25Q64FVSSIG-W25Q64FVSIG-SOP-8-...
