Dodging into Hormagaunts

In Tyranid missions, you're pretty much guaranteed to be surrounded on all sides by hormagaunts. This can easily become a big problem if any unblockable attack starts coming your way (a spore mine, a boneswords warrior jumping doing a heavy attack, a zoanthrope targets you for an attack, etc.), since hormagaunts act as obstacles, and they get in the way of your dodge rolls.

My idea is that if we roll into hormagaunts, then we knock them out of the way of the dodge. That way if we get targeted by something, we can actually respond to it.
