It all depends on the internal condition of the caps you are putting in series. If the unit has a bleed resistor in the circuit, then you may remove it, and add it to the caps as a series string, with 2 resistors in series to make up the original value, tying the center of the resistors to the center of the two caps, making an attempt to keep the right voltages appearing across the two caps. If as I began to say, the condition of the two caps, is that one has a different characteristic that allows a higher than rated voltage to appear across one of the two, then you run the risk of something going wrong, like a small explosion for example. Generally, although the numbers show that you can do it with a cap, its better not to do it with electrolytics unless you have no other options. But then know what can happen one day if one cap develops problems.
