The flagship books are doing good considering the state of the current market, but both are heading towards the sub 40k range. November's Action probably would been less than 40k if it hadn't been for the Oz Effect bump.
After Action Comics #1000 and at the latest, the conclusion of Doomsday Clock, if there isn't a shakeup of the creative teams, I see both books crashing in terms of sales and having a hard time recovering after new creative teams take over.
I agree that switching creative teams works better to stop a book from dropping to a certain point rather than digging them out of that point. However, a dramatic uptick beyond two issues is realistically reserved for a Grant Morrison or a Jim Lee.
Yes, unless there's a team made up of big names that also deliver unanimously well received stories, sales aren't going to increase by tens of thousands and remain at that level. But a different team may be able to stabilize sales in the 40k range for both books in the long run without having to resort to crossovers.
There's also the matter of how the eventual price increase and putting a stop to double shipping is going to affect sales. It's going to happen eventually, since not all writers can manage the bimonthly schedule.
I feel like the current teams have been bouncing along the side of a bucking bull already with managing the double shipping. The current releases make people quicker to try a title with its lower price, and makes it a little more hairy to jump off a subscription, since the issues come up so fast and people with a decent relationship with their LCS won't stick them with the two or three issues released after a drop.
Of course that last part isn't an issue with digital... but I also agree that the $4 monthly should be coming back pretty soon and personally I don't quite like paying a little more for something intangible.

The price of being a newly created character as opposed to an established character usually means their comics don't sell as well. Even though New Super-Man is critically acclaimed and has a loyal fan following which helped save the title from cancellation, Kenan still isn't well known enough. Which means his comic will struggle to break 20K again.
It really is a masterpiece, but like Lvenger said, this is what happens when you're a new character. Fortunately the book is doing really well in trade sales, Yang has said that was a major part of why the book avoided cancellation, but I still really wish DC had relaunched the JLC title at #1, rather than just rebrand it, which likely won't raise sales.

only about a 2k increase in sales for new super-man and the JL..really would have been better if they gave the book a #1 instead of continuing it.
Action Comics sales will only get bigger leading up to 1000 and Bendis.
Superman sales will increase with Tomasi back on art and it being the final arc.
Supergirl is still doing good in sales, sad Orlando had to leave.
