Items have been added to the Special Supply catalog exactly six months after they were available as random drops in the game. That being said, not a single Ranking Tournament reward has been added to the catalog. Right now, the catalog is featuring August 2014's items (added in February) and September 2014's items (added in March). None of the Ranking Tournament rewards from June through September (21 emblems, 3 skins, 36 nicknames, and 9 Special Aircraft) have been added thus far, meaning that the chance of the X-02 -Knight- being added to the catalog is probably zero.

That being said, the game's 1-year anniversary is approaching in late May 2015. My personal belief is that the Ranking Tournament rewards will be added to the catalog on a 12-months-later basis (like how the random drops are being added on a 6-months-later basis), or that the Ranking Tournaments themselves will be re-held. However, neither of these have been confirmed, so do not take them as truth. It's just my personal belief.

tl;dr No, Ranking Tournament rewards are not in the catalog.
