I designed a relatively simple +30V PSU. Output current can be adjusted via Rsense resistor. A -30V PSU can be build by use of complementary transistors and LM337.

I was thinking of adding a DPDT relay. One contact will be wired to high power low Ohm resistor that will be in series with the circuit right after the bridge. This is to limit the inrush current. Once the capacitors are at their peak voltage, a timer circuit will toggle the relay and bypass the series resistor.
Please comment, as your advice is valuable to me
