Thank you for your suggestion, but unfortunately the answer is will have to be no. Schall Transport Group mod is released under a non-open source license (yeah, I get it that the game is also proprietary), and for that reason I do not want to even look at its code for integration purposes.
"Private Use - I am not impossing any limitations on private use, if you want to modify my work, or create your own using parts of mine, you are free to do so, as long as this altered or derived work does not become accessable to the public."
I have read the license, and am aware of its contents, thus the original answer. Once again - it is not a Free Software/Open Source license, so as long as it remains as such I am not interested in adding integration towards that particular mod.
