Anyone more knowledgeable please correct me, but my understanding is that you can't really manipulate feats in K1. All the current feat effects are hardcoded. You can make new feats by manipulating the .2da files, but they won't do anything. The only use case is to use them to require the new feat for something else (ex. custom equipment/power).
If you are suggesting that the feat effects will just work through the hide item equipped, that could work (that's how Juhani's camo feat works).
The scripts you'd need are pretty easy, I can even send you mine as an example (they are based on the scripts from HK-47's repair challenges). To trigger them in the Ebon Hawk, you would need to add something with dialog (a character for example) that could trigger the individual scripts based on player choices.
How to add characters, computer panels, or any other dialog trigger to someplace like the Ebon Hawk is beyond me, so you'd likely need to look through mods that do that and try to figure out the process.
