Wheelbase is expected to be longer due to the bigger clearance.
Though doesn't taller headtube is to compensate for the future shock unit? HT length is an odd one, even comparing between the 2017 Diverge 54s and 56s, I'm just surprised at how big the difference is.
I guess the biggest issue for you will be the bars already 1/2 higher than you normally have. If it's worth anything, I think I saw some pro 2017 Roubaix went for negative stem to offset the height of the future shock, but it's not a pretty sight
+1 on thru axles, that's why I waited for the 2018 model instead of getting the 2017 model with SCS
