Pretty please, make it's upper torso a little wider, to 2-3 millimeter between arm sockets. Present mini, alas, too skinny and look like a column with arms.
Not so much, like on attachment, but somewhere between.
Sorry, the answer will be no. Three things come into play here:
First, the work is done and off to IWM already.
Second, it's not sculpt-by-committee. I see it much the same as fans wanting to push a scheme idea into canon through CSO; to avoid discrimination (and because you'll never please everyone), once work is started fan input has to be put aside. While you may want 2mm, someone else may want 4, and yet someone else may object to any increase in size. It's a no-win situation to accept any of it mid-stream.
Third, changing the width of the torso would require a complete reworking of it to keep the details in proportion. That would be far beyond the scope of this project, which was simply to modify the existing piece to the -7P variant. Bear in mind that you will be able to do much more with this piece than previous GHRs. With a more dynamic pose you may be able to change the "column with arms" feel without needing to add to it.
