Although I'm interested from an SQ-centric POV (to get KF miles), my question is in general, rather than for the specific example given. Can you book, through the airline website or otherwise without a 3rd party (e.g. travel agent), air travel where all segments are codeshared?
Why do you specifically exclude buying from a third party?
To answer your general question, yes, it is absolutely possible to book an "entirely codeshared trip", but it should usually be easier to do this via a travel agent than from the codesharing airline themselves.
