Here is where I could see the "hated" beginner corals thriving and doing 2 things. If you put pulsing Xenia, gap, pandoras, and all of those other corals in there, they would act as a nitrate filter. Who cares if they go wild. All of these can live in lower light, if not a toilet with ambient light. If you have fish that eat them, so be it.
The above is just a thought, as any decoration is going to require a ton of maintenance and provide no benefit to the tank. I will say that when I had a puffer dedicated tank, the Xenia and pandoras were on the menu, but they could not eat them as fast as they grew. It also helped me keep nitrates around 10 and po4 around .1 with a small fuge ran reverse light, 10% bi-weekly water changes and an undersized skimmer.
In addition, you may even be able to trade some frags into your local LFS for some credit and use that to buy food or dry goods.
