How about turning the whole transformer 90degrees and having the mosfets on the top like they are now, but put the diodes on the bottom??? Nice and symmetrical - me like...

The power tracks should not get that much longer, but the mosfet drains definitely will get shorter...

I would also move the gate resistors directly at the gates. They can be under the mosfets.

I'm trying to keep the TO220 devices on one edge of the PCB.

I can't move the gate resistors without making the current carrying traces smaller.
