I would think that you could cut a lot from that colony. The one caveat here is that the coral will slime up so running carbon to keep the water toxin free should be kept in mind.
The one caveat here is, as you know, this coral grows considerably fast and spreads quickly. Cutting it will not physically remove it. So if you want to free up a lot of real estate, you'll have to remove it at its base completely or cut it low on the base and smother it (like with epoxy).
I personally would keep the large colony in the back right, and remove the large middle pieces. You could surely find some buyers or maybe even trade it into your local fish shop for credit.
