suggestion for banshee boarding:

How about when you have the player board, kill the ai in the driver seat, make some small explosion, and have the player go into the hatch, but disable the driver flag for that seat, just enable third person and the banshee gun. Causing the banshee to go down since no one is controlling the driver seat. ( he actually is where the driver is suppost to be, but the image here is to think the banshee is broken)

E: then after a certain amount of time, have it explode.
