Feasibility of running mmdebstrap under Stretch (not Buster)

I was investigating using multistrap, but it has been orphaned.
mmdebstrap apparently has the desired features of multistrap but is available only in Buster.

I do not have the available bandwidth to install Buster.
In Stretch perl is 5.24.1-3+deb9u5 but is 5.28.1-6 in Buster.

Is it feasible to run under Stretch? How?
