This could be cool for a diorama, but the battlesuit's pose itself might not fit. When a pilot climbs out of their battlesuit, do you think it might assume a more low-power mode or something?
I kind of imagine the suit freezing in pose when the pilot disconnects, in this case she has decided to perform a tea ceremony before the battle to enhance her one-ness and calm any impetuous thoughts. She has carefully placed her shell on a rock, positioned to give her some shade from the harshest of the planets suns', but as she whisks her tea in its jade pot the sands begin to shift...
I am out of armatures for the pilot & will need to make arms, legs & head for her, nothing has the clothes & pose I am looking for, did you ever envisage a drones antenna being used as a step ladder?
After putting weapons onto the model
This commander is very weapons light, he's not the usual thing most will put in their competitive lists: shield generator, ATS, 2 missile pods (mainly for the 36" range) being jet mounted they leave the arms / front of figure unrestricted.
Then he'll have a bodyguard of 3 xv-8s': stim-jector <to soak the commander's wounds>, early warning override and a missile pod or cyclic ion canon - undecided.
