Couldn't you open it up and reverse just the field winding?

That would make it run the other way, not reversible, but
you could bring out the field wiring and use your relays or
H-bridge to reverse it.

The interesting feature of a series-wound motor is that
at low speeds it draws a lot of current and gives
you a lot of torque.
