I tried doing something like that with strips of plastic cut from 2-liter soda bottles. I got the idea from a guy on another forum who was using the bottoms of 20 oz. soda bottles as pots in his aquarium. Since they're food packaging the plastic is safe and it doesn't stand out much in the water, until algae starts growing on it, anyway. (shrug)
I don't know how it would have worked in the long run, as I changed 'scaping tacks and pulled them out after only a few weeks, but they were quite easy to work with as far as putting them in where I wanted them -- quite flexible. I imagine a certain amount of experimenting would be needed to get the widths and such exactly where you wanted/needed them.
