I quite liked the idea of that mod as well.
I have zero knowledge of the code, but tried and located the code created by Gibbs and incorporated it into newest public version files (0.5.3.5d), along with small updates - mostly changes to various numbers/formulas to reflect current state. Took me like two evenings, but it seems to work okay for me.
Did it just for personal use, but if perhaps someone would like it as well, you can download those two files here:

Of course all credit goes to Gibbs for the code(with small mutilation by me) and to the developer for great and fun game. If asked by them I will put the files down.
Cheers
