That's a badass kitbash. I'd buy her at retail for sure!
Only real drawback is that you'd have to buy half-a-dozen figures to replicate it. Most of them aren't expensive, but if you can't end up using the other pieces it's a bit foolish.
I did some more messing around with it. Using a different butt pack and only one bracer. Experimenting with putting a bipod on her M16A1.
If I can get the pelvis swap done I may do an ARW bio for her.
