It would be funny to see every one of Shibafu's girl with Shibafu's art style. It'll be like DD Fubuki talking to CV Fubuki (Akagi) and fighting alongside with BBV Fubuki (Hyuuga), all with little to no expression outside of a smile.
That and all the mix and match group of artist consisting of Bob, Shizuma, Yadokari's girls would all look so different and out of place it'll be Precure New Stage DX all over again, only even more out of place.
