I have looked into this and will have a WIP soon. Concept is basically simple:
1. 7ft tall - Werewolf stilts. These make your heels become the backwards knee and will raise you up 10"- 12".
2. Skin – You will need a foam muscle suit underneath and a spandex over suit that will represent the elite skin.
3. Head – It can be done in latex and combined with a bike helmet should be able to work fairly well. My plan is to combine it with a time trial bicycle helmet. Anyone who has worn a helmet or latex head can tell you the simple truth, it’s hot. If it was easy to make then someone would put it in a box and sell 100’s of them right? That’s the purpose of this forum to discuss how to do things.
4. Hands – By using some arm extensions, there are a few tutorials online that show how to make articulating hands, you should be able to get a few inches of reach and address the 3 finger problem at the same time. With the spandex suit you should be able to move your arms / wrists fairly well.
5. Bathroom – Only plan on being in this thing for a few hours so bathroom is not an option. Plain and simple, hold it!
6. Vulnerability – Keep several Spartans around to help you out. Also WEAR A CUP! Kids like to kick.
My target is to work on this project over the next year but these are not things you can simply throw together so plan on it taking some time. That’s why most people fail, because they fail to plan on a realistic timeframe to complete a project. It is possible and I also know a guy in Europe who is working on the same project.
Here are some concepts pictures only. The foam muscle suit would have to be made to match an Elite and the helmet / head assembly I think needs to be a bit closer aligned to address movement and weight limits.
So I challenge someone to take this project on with me and let’s see who can complete a great costume.
