Is it possible to add a man-portable anti-aircraft missile system (like the Javelin or Stinger or 9k32 Strela) capable of targeting mobs and vehicles from Valkyrien Skies and special missiles for it?

I have not figured out how to make any kind of homing projectile yet, but this is a very cool idea nonetheless. If I do someday figure out homing projectiles, I might try to make some kind of homing rocket launcher, but I can't guarantee that it'll happen.
