@Davidsch: Time is not a problem, this kind of calculation was widespread until the end of the Middle Ages (in some regions even beyond). You're right, the charset is a big problem. While writing the tool I'll put it in a configuration file 
The biggest problem is that the first "words" in the table (after the initial words in plaintext) should be word types. Only then one would have a structure comparable to the VMS. The newly created word types while generating the word tokens are extremely few (286) and would therefore not be significant.
