Sham was based on the Rocket Executive class from GSC, she didn't have a name yet. Because Sham was loyal to the Mask of Ice (Pryce), it didn't make sense for her to be working for Giovanni in FRLG, so Sird was made. Besides, Sird eventually evolved into her own character (will she ever show up again?).
Then the HGSS games came out and gave us Rocket Executives with names and characters, whose whole thing was being loyal to Giovanni and trying to bring him back. It wouldn't make sense to use Sham and Carl (proto-Archer) for those roles either, so Kusaka just introduced Archer and Ariana into the Manga.
There's no point in creating new characters based on Archie and Maxie. Especially since the fact that they look and act different is explained by them being fused together in the Distortion World and then being split.
Creating new characters for the Aqua and Magma admins makes sense both because they look different and because of the way the Manga admins character arcs went.
