A standing wave is the sum of an incident added to the reflective wave.
Isn't it possible to send two incident waves down an xline with
different frequences, and produce two different standing waves by having
some multiplicative relationship between the two incident waves and the
xline length?

Sure, it's possible but one wonders about the application.


Some repeaters use one antenna for two repeaters on 144 and 440 mhz.
Comercial transmitters do this all the time. Usually the transmitters are
in the same band.
