There was talk of using it in a kind of 'pass-through' mode where it
just gives access to the NAND flash, without doing the broken "disk
emulation" stuff. Looking at the datasheet of the PS3002, I suppose that
would be theoretically possible -- you just have to replace the code
running on the internal 8051 µcontroller. We'd need better docs on the
chip though, and we'd need to confirm that the 8051's program is
replaceable.

An ASIC which does just what we want would be a far better plan.
