There are plenty of ways to create more drama without resorting to such matters. In fact, we the fandom create most of the drama for ourselves. Look at the supposed "Sakura blushing" panel. That alone shows we make the drama more than Kishi does.
I hope Kishi doesn't try disturbing the lion's den with the love triangle. Especially with trying to remind people of Sakura's feelings for Sasuke. That is such a huge thing to do that could have such horrible outcomes. I can forsee many claiming "See? Even after chapter 632, Sakura is still the weak minded fool." Sakura is always hated by the some of the fans, I don't want to give them a good reason to.
The only way another pairing moment should occur is if you put Sakura in a point where she HAS to choose between Naruto or Sasuke once and for all. It really needs to happen and it really needs to be put to that test. So many times it was easy for Sakura to make a choice or do not have to answer the question, but eventually there has to be that moment.
If Kishi really did have even one panel; where she blushes over Sasuke, it will definitely cause more problem than it solves....all for the sake of one last drama? To be honest, we the fandom create enough drama with our own imagination. Kishi doesn't need to really do anything at this point and drama can occur.
615 proved that Kishi can give some big drama moments.
Imagine this moment coming where Sakura needs to choose between the both of them but the chapter ends with her flash backing with Sasuke. And then a 1 week break.
Drama from small things is created usually the day the chapter is launched but by the end of the day it mellows out a bit. But big drama moments.
And somewhere comes our biasness. We expect NS to become cannon and we see it as a part of the story but for the others it's one powder keg of drama. Look at what 631 did with the Kushina/Sakura parallel being confirmed. Everyone was bashed.
Regardless of big or small drama moments if Kishi keeps this moments to a minimum maybe the drama won't be that big.
