"If there's an Linux image for the H5 and an SPI driver, then Remora would be a potential candidate. "

That is not a problem if the board is actually worth using and readily available. 

"I think its probably less about ram, and more about graphics drivers. "  The more ram available the longer the backplots can be.

If you guys aren't married to ARM, might be worth checking out one of these:

I use them because they're small, still in production and have 2 NICs so I can dedicate one to a Mesa card. This board has 2 sets of GPIO, one is routed to an Arduino-like MCU, the other is direct from the CPU. I think the Arduino chip connects via a USB bus so it's probably not super useful in RT applications but the CPU based GPIO is kind of interesting. I posted about it here

Nobody shot it down as being unviable, but no suitable HAL drivers probably exist for this type of GPIO.

In the next year we will start to see multicore RISCV boards with 1GB of RAM for ~$20 that can run LCNC and a HD GUI at >30fps. These combined with microcontroller versions of RISCV's, STM32, ESP32 and the Lattice FPGA colorlites will give us plenty of low cost options fo simple LCNC machines.
