I think you've given it a steer with the accent and the harmonies in the chorus so it sounds like it's a country/bluegrass number already. But it's pretty strong so could probably take a slight change in style.
However, I like the feel currently so I think I'd go full band and stick with a country feel, for a full release and then have an acoustic version for live or stripped back recording. I can see it on one of those unplugged sessions with a couple of acoustics and singers, acoustic bass and a drummer sat on a box (do they call those Cajons?).
Cool stuff!
