It seems that the theme of Formal Craft, Imaginary Around, and Limited Zero Over is Rin, Sakura, and Shirou at their maximum potential as mages. Sakura learns to control her imaginary number magic. Rin masters all magic basics and the Tohsaka family’s gem craft. Shirou has mastered projection. It’s possible they reused Shirou’s CE design for Muramasa, as the CE was in the game before Muramasa.

The designers may just have decided not reuse Rin and Sakura’s designs for their demi-servant forms because they didn’t match the aesthetic they wanted for the servants.
