    If you tried to connect them either way, your driver would still be too much power for the tubes, and they would have a short life.

    If you connected them in parallel, the current through the tubes would not be balanced unless the driver was designed for that; so one tube would burn out very quickly.

    If you connected them in series, the voltage required to ionize the tube would double; the tubes may not light at all.

    You need to match the proper driver(s) to the tube(s).
