It might, but seems a little high. That would give you ~380V raw DC, which seems like a lot to burn off for a 300Vdc output. I know you need some overhead for the GR PSUs, but that seems a bit excessive, and you would need to make sure you have adequate heatsinking for the pass devices.
I'd wait until someone with more experience with the HV supplies weighs in however.
I did a board like this years ago for 31DQ10 shottkys (or anything in an axial package) that I've used on most of the GRLV PSUs I've built, etc. I attached the gerbers for this board if you want to have some made for yourself. I would prbably do these in 2oz copper instead of 1oz. Here is a screenshot from JLCPCB's gerber viewer on their site:
