Great idea man! the only thing i can think of that might get in your way is probably the cost. How do you plan on manufacturing these parts? distributing? and how will you design say the "custom" bumpers for a honda civic made by tamiya, and a civic made by fujimi, does that mean you will have a selected line of parts that can only be used with their respective manufactures? eg. tamiya, hasegawa, fujimi,aoshima etc. let me know what you think.
