I can't see any reason why using a ceramic capacitor WOULDN'T work just fine (if not better - but one wonders why that wasn't done in the first place) Alternatively wiring 2 identical electrolytic cpacitors anode<>anode (or Cathode<>Cathode - it doesn't matter which) creates a bipolar capacitor with 1/2 the capacitance of one of the capacitors. (IE: you'd need 2x20μF capacitors to create a 10μF bipolar). It's often done in speaker crossovers, I believe. Rated voltage of each capacitor would need to be the same, I would imagine (25V in this instance). Depending on the location in the drive, you might start having challenges fitting them in.
