Great idea but 2 x 4 was the smallest PT lumber I could find.

As dpb says, grain orientation would prevent the joint from being
structurally sound anyway, so perhaps a steel frame or maybe
some "L" StrongTie joints.


Just be careful how far you take principles. Sure - a cross grain joint is
inherently inferior to a joint where the grain runs in the same direction -
but will you ever notice that? For centuries, cross grain joints have been
in use and have served very well. You can take the theory too far and get
all caught up in what you should not do. Net result - analysis paralysis.
You'll never build anything. The governing factor should be whether the
particular joint, or technique is sufficient for the task at hand, not
whether it is the best theoretical approach. A good guiding light is the
preponderance of evidence of eons of time. Ignore all the rest.
