Great Idea! 
I know what you mean - I am just starting this fine hobby and the wife looks at me weird everytime I talk about a new peice. Kinda like "do you know what you could buy for that much money" 
Then again, she is supportive and listens to me talk about how I am going to make this... and how I am going to paint that...
But... like you I would not want to push my luck and build two suits - although the multiple helmets are an interesting idea...hmmm :evil
