Thats a good idea, only issue is that the fists are faced down and too near the legs so it wont be super simple. I guess you can either twist the hands round 90 degrees or try to put on a shield at an awkward angle.
This is awesome to watch this army getting built. I'd love to have a proper vintage metal army like this. But me 3D printing proxies will likely be my only way to afford it. Still trying to get my hands on the rules. Thank you for sharing all of these videos with us.
The way I see it, there's no shame in opening old model blister packs. Minis are meant to be painted and played with. It's what they were intended for. Not sticking inside yellowing plastic, unloved, for all eternity.
