And both Tim and Cyrille have commented that mods to the 50g ROM were extremely difficult as it's highly patched state is very frail and nearly any change led to other undesirable side-effects, etc. So, many man-years of effort by folks with System-RPL and likely both Saturn and ARM assembler experience would be needed. Not impossible, but also not cheap.

This is why my preference for a "modernized" HP 4X would be NewRPL or DB48X running on modern hardware, along with an emulator similar to EMU48 that can use ROM 2.15 to allow the use of "legacy" programs and libraries that contain SysRPL or assembly code.
