Well, I sort of have the same problem. I got a 16g tall (think it was custom), and I can't find anything to go in there. Hubby thinks it's hideous 'cause of the fake oak trim at the top and bottom. I don't want to do schoolers 'cause I'm afraid they don't have enough swimming space laterally. I had a small goldfish in there until I started setting up my pond, but I had to sell him back to the LFS because he grew too quickly (I'm a procrastinator). Then I had some other small fish in there for a couple weeks until I got my 75g set up and ready to go.
What are the dimensions? Mine has a footprint of 12 inches by 12 inches, and 25 inches tall. So, it's very tall without much room at the bottom. If the one you are looking at is not quite as tall and has a longer footprint, I'd consider it.
But, IMHO, I would not do it. It's hard enough to stock a regular 15g, let alone a tall. Plus, if you don't like the looks of it anyway, you'll just end up regretting it.
