That was done because Mira Furlan wasn't doing well with the full Minbari makeup so he she got a hybrid look, which was the better outcome given similar problems are what led to the actress who played Zhaan from Farscape leaving that show. But even before the human/Minbari hybridisation Delenn's appearance in the pilot movie was extremely androgynous when compared to later appearance in season 1. JMS had intended for the character to be androgenous enough to be played by a male actor at first then change to female after using the triluminary. As it's now $CurrentYear+8 you can expect the reboot to not only go along with the original idea but to do so with all the subtly of a depth charge in a teacup.
