I haven't done it, but I've seen it. Pond liner folded in place and stapled to the wall and inside of the stand. It could have been done more neatly than the job I saw, although there is a certain minimum messiness to the folding of excess liner at the corners. There is a pond liner tape that could make it look better. If I had what I saw under their tank under my tank, I would not have shown it to anyone. It did work and created the maximum size sump that could have been under the tank.
I left the two sides in plywood since this allowed me to bring the rockwork right up to the sides. I also brought the diagonal window up so that the side walls were 24" instead of the 12" you often see on plexi-pentas. That gave even more room for rockwork and increased the gallonage of the tank, saved me a little on the cost of the glass, and did not IMO detract from the impact of the tank even from across the room. It greatly enhanced the impact when you were up close and looked in, with all the rockwork wrapping the tank.

Nice tank stand so far, I'm sure this is going to be a nice build. Also, it looks like you live in a beautiful old house. You should post a pic of your house too
