Yes, personally I think they might. As the 6/7/8 design fades out, the range is definitely skewed toward very large phones. I would not be surprised to see a new 7 in the spirit of the SE. Re-use the old 7 chassis to take advantage of depreciated tooling (maybe move assembly to India - Apple strategically need to assemble something there, which used to be the SE), add the latest A-series chip (remember the SE launched with the A9 which at the time was the latest generation), leave out some features to cut costs and maintain differentiation of the top end phones (eg no wireless charging, a lesser camera), launch around March 2020 as the iPhone 8 starts to get long in the tooth....
