The hard part is that there's not a single reference design
there. There's some pattern, but it's not at all something that can be
made generic, because to a few exceptions, no one uses the same
regulator to power the same thing, and with the same constraints (that
directly depend on the stuff that you have connected on the other end
of the regulator).

So any mechanical change is not something that can be done. Especially
for something that might blow up your board.
