This should work fine. You might put a very small resistor either in series
with one of the transformer secondary leads, or one of the bridge rectifier
leads, to reduce the current surge. Something of a few tenths of an Ohm
would probably be right. Otherwise, it should be fine. You may need a
little more capacitance there, you will have to evaluate the voltage ripple
when the stepper driver is drawing the maximum current.
