Nope. The free Odyssey that was given away is in the fleet shipyard, or it will be when fleets hit Tier 5, and it should still be "free" (no FSMs, only fleet credits).
However the three ships in the Odyssey bundle already have ten console slots and higher hit points than other T5 ships, like the fleet ships, so there's nothing to upgrade them to.
And if you're looking in the Zen Store, you're not looking in the right place for Fleet ships, anyway.
Odyssey Star Cruiser has 9 consoles and was available through an event months ago and 200k FC through Tier 5 Shipyard. C-Store Odysseys have 10 consoles and is available for $25 or $50 if you buy all 3. The lockbox ships also have 10 consoles. Therefore, anything with 10 consoles is considered as a fleet ship as far as the devs are concerned. There will be no fleet version of lockbox ships and there will be no fleet version of the Odyssey.
