I may be a month late into this, but just as riendly consideration for Kazugeta:

[i]Officially[/i], as in the history the Imperium does acknowledge, the two legions were lost before the Drop Site Massacre. Also, its confrimed that only Lorgar and Magnus were interested in aspects other than warfare.

Your theory for a Tau-supportive Primarch would work if you could account for the Tau's inferior jump drives and lack of independent thought, outsidethe Farsight Enclave separatist movement. One primarch could have come upon the Tau and decided to give them a nudge in development and imparted the 'Greater Good' philosophy upon them, but records state that both were purged/forgotten.

Again, your theory could work, but only to an extent.
