What I'll do for now is just leave the armor upgrades as separate inventory items that are stored in the armor, and attach the effects to the individual armor upgrades. It should work, as my players like to swap out upgrades on a regular basis.
Thank you so much for figuring it out, though! There's really so few extensions to use with Starfinder, I was excited to see that yours would work with it.
