That's the question: why you want to build your hub in a "non-transferable" airport? You can open your home office in this airport but building hub in this airport seems to be a trouble when your airline is growing because most of your passengers are direct connections. You can't grow further if you don't get out of this airport. Try to find some secondary airports that can still be used as your hub as well. Good luck.
Nah not that, there is an idea I suggested in AGEX thread in General forum section, similar to this one. Build terminal (along with a runway) and get additional slots. Depending on how much you invest (smaller terminal, smaller runway) you would get less or more slots...

So an airport like Los Angeles would have 29 runways instead of 4? And those runways would be built where exactly? On an island in the Pacific, which still needs to be built as well? And why would a long runway give you more slots than a short one? Besides, with 29 runways, how would you solve airspace congestion? How would you plan SIDs and STARs for all those runways, especially the middle ones? By having an airplane fly for three hours straight ahead before being allowed to make the first turn?
But it would still be good because in some airports like Dubai you can't get a slot at any time.
Plus quite a lot of transfer airports are very big so you wouldn't be able to get a slot, even to transfer
As you said, it's hard to get a slot. So, when you have the chance to get a slot, stick with it. Try not to build a hub in airports like LHR, LAX and CDG because they are mega airports and everyone would like to connect to it. It's simple as it happens in the real life as airlines have to keep their landing and departing slots instead of just let it go for others.
