Oh god, don't do that to those poor mosfets.

You're confusing switching time and switching frequency. You want the minimize the % time that your mosfets are partially switched (with consideration to your other components). Just to ballpark it, try 50kHz and see how that affects your inductors and capacitors.

If you were switching at 10Mhz, you would never be fully on or fully off and you'd be burning insane amounts of power in the mosfet.
