No, the wheels will never tighten properly, the ball seats on the lug nuts
are different size and angle. Your lug nuts will bottom out against the
rotor or axle flange before clamping the wheel on steel wheels, on the
aluminum ones the ball seat of the nut will not properly mate to the
corresponding seat on the wheel, in a short time the seat will tear up on
the wheel and you'll have a lose wheel condition.

Not true, the wheels are hub centric, not lug centric. The lugnuts are
not acorn style, but flat bottomed.
Yes you can interchange. It has been done many times safely.

I tend to think your response is probably more correct than the previous
one, in part because the original wheels that Ford put on my 12mm studs have
14mm holes in them and the nuts are flat as you say.
