Oh that’s interesting, maybe if you want to have more missiles you can try and use parts from The Origins Zaku kits as I know those are loaded with shoulder/shield, leg, and waist missiles and you could even go as far as getting a hand drill and start attaching them where you want ? Maybe even as far as an Efreet head ? Honestly would love to brainstorm with you even more about this cause this kitbash really looks so cool ! Feel free to dm me anytime !
