I'm trying to envision exactly what you are talking about. I think it might be possible but only on a vintage bike with low end parts. I don't think it would work with a cartridge bottom bracket and most seat posts will require drilling a hole big enough for the cable with an eye fitting. That sounds to me like a mega bad idea.
If it was my bike I'd just use a piece of 3mm cable around the seat rail and a seat stay or, for the kind of retro look that I like, use a section of old bicycle chain linked back together in a loop.
