I would still say drive it from both sides, just get another motor and trapazoidal screw and it will be a much better solution. It may cost you a little bit more but at least you know it will be right!

Just wire both motors to the same driver card, so you won't need to spend more on electronics.

I dont suggest connecting both motors to the same driver.
This can cause problems with the driver and will also void the warrantee of the driver.
As an example of the problems you will see is that if the driver has any anti resonance circuitry this will most likely cause this to not function as expected.
You will also have issues with BEMF.

If you go with twin screws, I'd drive them both via belt from a single motor. If you use two motors and slave one to the other and one loses steps you will get racking. If one stalls, you could get a broken machine.
