Funny you mentioned stealth. The icing problem got me curious and googling. There are anti-ice or deice systems, and then among them there's a type that overlaps with what makes a plane stealth: Coating/Textile. Now, if you're thinking about balancing the gameplay, a plane's stealth capability could be reduced if it has anti-ice surface.
