Weapons that Capture Planets

[Ed Kolis]

Is there any way to make a weapon that acts equivalent to Boarding Parties or Allegiance Subverter, only it works against planets - that is, it initiates a ground combat as if it were a bunch of troops being dropped? If not, there should be - imagine Planetary Allegiance Subverters and Borg Planetary Nano-Assimilator Warheads!
