Found ic codes.. the mosfets can upgraded with better easily.
But in general needs optoisolation / overcurrent protection / enable pin / higher clearances in copper traces and better mosfets

7402 seems to have daisy chained NOR's, it should be possible to disconnect some and use for enable.
And for higher voltage, something must be done for MC34063, probably cutting the trace and supplying another 15V to it separately.
