Thumbs up for the fet driver. But one more thought if you still want to bear with me. Works nice for 12V. But ppls may go for 24V in which case it may be something to investigate, for example there are lots of mosfets with Vgs max of 16v or 20v. So this may impose other kind of restrictions on mosfets, like Vgs max > Vin. So depends if you want the board to be usable with 24v psu + normal mosfets. If so, then perhaps a onboard regulator can make 12v just to supply gate voltage, and in Vin is 12v it will output Vin - regulator dropout. Even if its not LDO and has some 3v drop, still 9v quite ok for gate voltage. Its just a thought or a consideration, something to think about.
