Probably been tried at least.  Sounds a bit like a mix of ranges and
detection; Greg Johnson or Rune Johansen, to name a couple of people, might
have a explanation for you.
I'd say you would use #switch and #range for the main timing and then a #if
conditional to see when a object vector is near the projectile, like
#if(ObjectAreaPosition*ProjectileAreaPosition<ContactDistance).  Takes some
squaring of the area around each to know what space they occupy.
I would think trace() could do fine for this, especially because of the
non-spherical boundaries you would probably want to be using.  But then
there's all the rest involved, such as moving the projectile in the proper
direction.  Long story short, I have yet to do that myself.
