Default 2 IC SMPS for car audio, how stupid is this?

I was thinking about a power supply for a car audio amp using a 3886 (or similar) the other day and wondered if it is possible to use 2 separate controllers for each rail rather than a traditional smps.

On one side would be a boost switcher and the other would use an inverting controller.

1) Will this work
2) How stupid is this?

Years ago I saw an article in 'Electronics Now' (or whatever it was called at the time) that used 2 boost converters for the rail voltages.
Sounds do-able to me.
