I haven't tried it, but I can make some observations. The MAX1771 isn't connected directly to the output circuit, so it's not likely to suffer from a problem. The current flows through the inductor which will accommodate a momentary short circuit caused by the capacitor. In short, it shouldn't be a problem. Bear in mind that the effective capacitance of a modern ceramic capacitor is much lower with a DC bias near its rated voltage, so you would need to use either capacitors rated for 5x the output voltage, or about 5x the desired capacitance. Some capacitor data sheets publish this reduction in capacitance as a function of bias voltage, most don't. Look for it.
