I freely admit that it can happen in your mind (like
leaping tall buildings at a single bound). I do not
believe it can happen in a real-world situation. But
if you can demonstrate lossless transmission lines
and lossless inductors on the bench, be my guest and
probably win a Nobel Prize in the process.

An intriguing thought experiment is to take several
of these sections with stored energy (with the proper
phase relationship) and connect them together. Do
the reflections present at the ends of the short
sections suddenly disappear when the sections
are connected to form a longer line? Are the
reflections now only occurring at the ends of
the longer section?

Reflections are impossible except at physical impedance
discontinuities. There are zero reflections at a point
in a smooth fixed Z0 section of transmission line. Cut
the line and you get 100% reflection. That's why your
assertions of "no change" don't make sense. You would
have us believe that short circuit to open circuit is
"no change"??? If that is true, there's "no change"
between a shorted 1/4WL stub and an open 1/4WL stub.
