And the ISD model is already a fairly hefty chunk of plastic. FFG would need an astoundingly good reason to make something that is EVEN BIGGER, due to the financial considerations that I mentioned earlier. X-Wing can get away with piles of weird corner cases plucked from the depths of the Legends lore, since they are much, much smaller & cheaper models, and thus easier for general consumers to justify in picking one up to play around with.
We can get stars in our eyes all we like about what we would like to see in the game, but at the very end of the day, FFG is a business, and needs to be certain that any new release it makes will end up making more money than it cost to produce. A very large and expensive model that does not have broad, widespread appeal is a massive risk that I cannot see as a viable option over far safer bets such as the Tector and the ever-popular Venator, both of which are fully canon.
I'd say that the Venator holds more of that appeal than the Tector does, as it is a more immediately-recognizable design than a modified ISD hull - and thus it holds my vote for the next large-base Imperial ship we will see, regardless of what the contents of wave 7 end up actually being.
