If using the ps2x2pico firmware, wouldn't you want to control (the HV side of) the level shifters with gp13's as shown in the github 'schematic'? Otherwise you'll face the same problem you had when not using pullups to gp13. I like the idea of putting this in a tidy little converter board, it's a good plan.
Edit:
Also, for greater compatibility w/ existing picomites in the wild, what about adding some jumpers and locations to populate pullups to bypass the level shifting and allow for the circumstance of only needing to directly connect to another Picomite that does not expect 5v level signals?
