If not, isn't that proof that the two original

no, because you have done a non-linear operation on them by converting to
powers. obviously at the start 'a1' and 'a2' are separate.

If V^2/Z0 and I^2*R cannot be reverse superposed
in reality, doesn't that imply than neither can V
and I be reverse superposed in reality?

Doesn't a real world EM wave require ExB joules/sec
for it to exist and to have an associated voltage
and current?
