Using Super-Spun Article With Variables To Make A 100+ page site?

I had this idea the other day while doing KW research.
Wondering if you have ever seen someone using a super spun article with variables in it? Like lets say you want to rank for every long tail of T-Shirt. elvis T-shirt, wolf t-shirt, bandana t-shirt etc.

Each has 2k volume and 0 competition. So why not make 1 super spun article with t-shirtX for each long tail then use a script to sub it in.

It seems like most niches has a possibility for this technique to expand their site by 50…
