with regards to feasibility, this would be a straight port of the unique gases from tg and presumeably not an overhaul to the main atmos code, so wouldn't be as hard to implement (although i'm not a coder so i may be wrong.) In terms of balanncing this wouldn't have a massive impact as you'd need to be a fairly competent atmos tech to create mixes like stimulun and it'd take a while to prepare as well as making others in atmos suspicious. Tritium also requires some setup to produce in large quantities, so it wouldn't have an early round impact in the case of antags. Atmos technician currently lacks flavour and is often left unloved, justice for atmosia!

Currently, playing atmos tech as a non traitor is not particularly exciting and largely consists of waiting for a hull breach to occur or for someone to try and flood plasma or such. Porting gases from tg would add more interest for both antags and non-antags as non antags can mix various gases, including useful gases like pluxonium or help science by making tritium whilst antags have a variety of useful options instead of the aforementioned plasma flood ie making stimulun to use as internals in combat.
