Like FTS Geko said, the Rebels TIE Fighters are very small. You can tell on that short teaser of Zeb around the landed TIE Fighter.
My Gozanti Cruiser is bigger than the one in rebels. Mine would be around 70m at 1/270 scale.

If you got all ships at the same scale this is what they will look like (official sizes)

Don't forget the transport is already at an adjusted scale, and if at the same scale as the fighters, would be about double it's actual size. So if they make the Gozanti into a "huge" ship, then they will either have to make it at a different scale from the rest of the huge ships, (which would then look weird to me), or make it at the same scale as the huge ships and have it end up being SMALLER than the falcon.

I think it's important to keep in mind that epic scale, for the two ships we have so far, isn't necessarily LINEAR as a lot of people seem to think. (It's been a while, but back during the frenzy of MUST HAVE STAR DESTROYER posts, a bunch of people plotted the two scales on a straight line and interpolated that with continued adjustment, a Star Destroyer would be "perfectly legit" at, like, three inches longer than the CR-90, or something similarly ridiculous.)

My understanding is that the epic scale is more in tune with "what feels right on the table." So I think it would be perfectly acceptable to have an official Gozanti carrier that is pretty close to proper 1:270 to accommodate the mounted TIE Fighters. There might be a little cognitive dissonance looking at the Gozanti and the Transport right next to each other, but frankly the YT-1300 and the CR-90 squick me out a little when they're right next to each other. I think, miniature-wise, a Gozanti would be a FINE Imperial corrollary to the Rebel Transport, and it would (ideally) come with two ESB-Blue TIE Fighters with a host of new pilots and swag, to correspond with the Transport's X-wing.

All that being said, as cool as it is and as much as I would be happy to purchase an official package, I've really never been able to figure out what the mechanics of a carrier like that would provide that the game actually needs. Do we REALLY have a pressing need to make the Imperial player skip his first turn or two while the Ready Pilots are jumping into their ships and disengaging whatever locks keep them from flinging off into the void whenever the carrier jumps to/from hyperspace? Or, if we're not using an in-game carrier mechanic, then what else does the Gozanti provide to make up for the really awkward space it inhabits, scale-wise?

At placement you assign up to 4 small ships to a Gozanti

At standard ship Activation you can choose that they remain Docked

After the Gozanti performs its maneuver it can perform a Launch action

Then you place any of those 4 small ships with range 1 of its base, then they perform thier Activation Phase as normal.

This would allow you to move those fighters up to 15 bases from the start area in one move. Which could be an interesting tactic.

I have an idea for a carrier action that might be cool, I've posted it a couple times brfore.

I stand corrected, that sounds like it could be a lot of fun.
