If you're aware that it will be unlikely to take the world by storm, then complete it regardless.

You'll probably learn interesting things, and have something you can use either for real, or as you say for a portfolio-project.

FWIW I wrote http://github.com/skx/templer for similar reasons, in my case annoyance at how poorly other static site-generators handle symlinks.

I use it these days on several sites such as http://lumail.org/ & http://tweaked.io/ both of which other people have contributed to, which makes me think the barrier to entry wasn't too high.
