Nanami's "alt form" makes it into the "Figure-Rise Standard" like; showing off how Bandai's MS Girls evolved from "loose-fitting nightmares with bobble-heads."
Her "weapons" aren't exactly what you'd find on a regular HGUC MS, but she has several ports on her arms, shoulders, and leg armor to connect to weapons that have available sockets.
Combining the parts of the Gundam 00 with parts of Destiny Gundam sounds like a good idea. But the original HG Destiny Gundam atleast had the "Light Hawk Wing" effects with it. Having this and then having the extra parts in the "Higher Than Sky" version financially feels like a bad idea.
Also; the blue fins on the front leg flaps get in the way of the arms. The sword guns on the Gundam 00 Diver was already a busy area as is, but dang.
