I have now generated every possible combinations from all 14 words. It took lots of time and lots of programming.
Now I really need your help in order to get this into addresses. I want a efficient way to input seeds and get addresses from them.
Any takers? I will make sure there will be a reward for contribution. I am really tired of this right now

If you want I can give you a program that works like that:
generate_address file_input file_output
where file_input contains private key in hex format and file_output contains addresses in hex format.
I have to modify my program that generates only consecutive addresses.
What kind of speed do you need? It is enough Python or you need a C program?
I have now solved this problem with a modification to the BTCrecover code. It now takes my custom-generated seeds as input, and then outputs if any of the addresses from that seed is found on blockchain.
It does about 25k per second, which is not lots, but it is sufficient.
