For the love of Science!
It would, however, require you to do some considerable remodeling and/or start-over. Lots of work, but it has been going for almost year now, and no problems.
I don't top-water that terrarium, because it was designed to house a small reptile, and I didn't want our hard water to make the glass dirty. It worked out very well.
For the 'feet' I used uniformly sized plant pots. Anything will do, really. The 'floor' is called egg crate light diffuser. It's pretty cheap, and you'll find it in the lighting section of most big box retail hardware stores.
Wrapped that with some screen to keep the dirt above, and filled in the cracks around the edges (near the glass) with sphag. Laid out the rope (Rope needs to reach down to the reservoir to wick water up into the soil). Cover with dirt.
What you can't see in these pictures is a 1" tube that goes from the reservoir to the ceiling. It was necessary to cover it to keep the critters from getting into the reservoir, but plants aren't likely to slither down there, so you could probably do something a little shorter.
