Yes, I was alluding to it in my post. I did successfully build a MOSFET driver (to drive a big MOSFET for a DC-DC converter) using two tiny MOSFETs (tiny as in sot23 package) in push-pull configuration. I found two MOSFETs that did barely overlap. It seems to work well. And the power dissipation was very reasonable at 42kHz. Note that I am merely a hobbyist.

Using non well matched MOSFETs resulted in a rapid uncontrolled atomization of the MOSFETs.
