Technically yes, for now at least - although from memory I think G'raha tells Urianger that the concepts of time travel were developed out of certain events that happened during the WoL's adventures, implying that we historically did them.

But again, canonically we're supposed to have done the quests as they become available to us, and the time travel plot has opted to treat them as done rather than try to convolutedly follow the maybe-or-maybe-not approach of the "present day" MSQ.

Also, Omega is an "only the WoL could do this" due to Midgardsormr's involvement, and Dayan's expository talk at the wrap-up of the Alexander story seems to rely on our plot significance.
