Some cool ideas here! There are a couple of places where you could opt into some Mothership-isms, to look a little slicker. For example, the Flesh Stitcher could be -5 Speed, rather than 'dex', or the Strength Check to escape the curator's pin could be a 'STR Check [-]' denoting disadvantage, rather than being at -10. I also caught that the Foundational Relic table has a d10 column, but only six entries. Perhaps two could be merged, and it could come down to a d5 table? The unspoken rules of Mothership Modules seem to be resistant to rolls other than d5s, d10s, and d20s.
One final Mothership-ism: Armour is usually represented as an AP value rather than a percentage. P.28 of the PSG has the details.
The 'magic items' are all really neat; I could see reaching for this module to use the relic table if my players went really off-road one session. My player brain saw the monofilament talons and immediately thought, 'Aha! I can cut my way out of this tomb into the alien past!' If you end up doing a longer version, I'd love to see more about the moon-bird-curator culture.
