LM5143-Q1: Configurable 1, 2, 4 phase design

Part Number:LM5143-Q1

Hi Support team

I am working on a design for my customer that is a bit unique.They want a configurable output with constant power, from a 48v DC input, The outputs either 24v at 2.5A or 12v at 5A or 6v at 10A. I think I can do this with a multi phase controller and use the same output inductors and same output caps by changing the switching frequency with a multi phase controller. So for example if i run the switcher at say 1MHz for a 24v output, one phase only, or at 500kHz 2phases for the 12v output, or 4 phases at 250KHz for the 5 volt output. 

Is this possible with the LM5143?Or is there another device you would recommend?
