Not using bty, but you can get the coordinates of the boundary via
par("usr") and draw boundary lines individually by code like the following.

plot(0,bty="n")
bb <- par("usr")
abline(v=bb[1:2],h=bb[3:4],lwd=1,col=2:5)

(You may get in trouble with large line widths and clipping, in which
case you probably want to use segments(...., xpd=TRUE), although finding
the right selection of the four limits  and putting them in the right
order can be a bit challenging.)
