Quad 405 with MOSFET PWR transistors

Hi everybody.

I have an idea, but I don't know is it good or death way.

What do you mind of creating Quad 405 amplifier with Mosfet end transistors, or all FET style? Could it work?

What about combinating the quad 405's (I have build 14 in last 4 years to friends, and theese work correctly) stability with linearity the FETs. What like of sound would be of this?
