A few modding questions

Is it possible to create a mount which affects an arbitrary ability of a component, such as Movement Standard (for engines)? This would be handy in creating "heavy engines" for use on large ships in mods using Quasi-Newtonian Propulsion!
Also, is it possible for script code to retrieve the atmosphere type of a race? This would make the creation of an equivalent of the SE4 Colony Tech Mod rather trivial!
