One problem; The tau did not exist at the time of the great crusade. They really only came into prominence during the 41st millennium.

I have a few diffrent ideas about the Lost Primarchs, but one idea could relate to the forgotten; what if he never appeared. If the Emperor could never find one of his sons, he would eventually purge their memory so no one knows of his failure. This centres around the idea that the Primarchs were tossed into the warp, where time is meaningless; what if one got sent backwards or forwards in time by thousands of years? Could one appear in 40k?
