Changing any of the dimensions entails designing a completely new die...
the CAD design time, toolmakers time, EDM time, etc. wouldn't be effected 
by such a time.  Most people don't understand this.  Mucho $$$

Ever since the introduction of projected 3D slides, aluminum has stood 
the test of time.  It really is the best material to use.  Paper and 
plastic both have their problems.  I don't mean to start an arguement 
near, search the archives, or better still ask those who do a lot of 
projection.

Tooling is expensive, however new dies would probably last for a long, 
long time.  As one toolmaker told me, "Dennis I can make anything if you 
are willing to pay for it."
