Personal Opinion: Asking for a lot here, 501st may have been the main lore battalion but that doesn't mean that they get more stuff than the other battalions. The only part of this suggestion that seems rational is asking for the medkit, but as Banjans said. Kix isn't special.
Tester Opinion: Would take some time to implement, on the low part of the list to be done, seems to just want the buff to feel more special than the other battalions.
Pros: Makes TC looks more powerful and better to be in, 501st is happy, etc.
Cons: Asking for way too much, trying to get an advantage over the rest of the battalions/sub-units, giving buffed weapons to certain people.
Overall: -1
