Green Lantern/Silver Surfer was never canon in the first place, being a crossover. Celestial Quest was the true Thanos as Mistress Death recognized him as such.
As far as 'Celestial Quest' goes...again, you're wrong. It was not the true Thanos. The proof is in 'Infinity Abyss'...you can choose to ignore it if you wish, but that's Thanos continuity. It's even been verified in his Handbook entry. Plus, as per more recent developments, even the most cosmic entity can be fooled by a Thanosi, (see She-Hulk).
The Walker story was the only appearance by the true Thanos in that time-frame.
